Travel Questions and Answers

Answer: B

The objective is estimating and measuring work as a preparatory step, keeping in view the development of quantitative skills in later stages.

One general objective in the NCERT EVS syllabus is to emphasise design and fabrication, estimation and measurement, as a prelude to the technological and quantitative skills of later stages. Looking at the technology, design and use of metals in old buildings under the theme 'Travel' asks children to notice sizes, proportions, materials and how things were built, which is exactly this objective.

Writing a survey report, filling in a map of buildings and identifying directions are activities, not the general objective the theme serves, and they do not match the focus on technology, design and metals.

Answer: B

From Delhi, Gandhinagar is south-west and Patna is south-east.

Delhi lies at about 28.6° N, 77.2° E. Gandhinagar (about 23.2° N, 72.6° E) is further south and further west, so it is to the south-west. Patna (about 25.6° N, 85.1° E) is further south and further east, so it is to the south-east.

A glance at the map confirms it: Gujarat is on the west coast below Rajasthan, and Bihar is in the east, below Nepal. The other options put one or both cities to the north of Delhi or swap east and west.

Answer: C

With respect to the school at Y, the house at X is 100 m due west.

Trace the route. From X you go 125 m south, then 100 m east, then 125 m north. The southward and northward legs cancel, so the net movement is 100 m east: Y is 100 m east of X.

Seen from Y, the direction is reversed: X is 100 m due west. The option 100 m due east is the position of Y from X, the reverse of what is asked. The 125 m options take one of the legs that cancel out as if it were the final displacement.

Answer: B

The average speed was nearly 38.5 km/h.

First find the journey time. From 22:30 on 4 June to 22:30 on 5 June is 24 hours, and from 22:30 on 5 June to 04:30 on 6 June is 6 hours more.

\[ \begin{aligned} \text{time} &= 24 + 6 = 30\ \text{h} \\ \text{speed} &= \frac{1145}{30} \approx 38.2\ \text{km/h} \end{aligned} \]

The exact value is about 38.2 km/h, and of the options offered 38.5 km/h is the nearest, which is why the question says 'nearly'. The other options would need a very different time: 1145 km at 42.5 km/h takes about 27 hours, and at 36.5 km/h about 31.4 hours.

Answer: D

Gujarat lies to the north-west and Bihar to the north-east of Telangana.

Telangana is in the south-central Deccan. Gujarat is on India's western coast and lies north of Telangana's latitude, so it is north-west. Bihar is in the east of the Gangetic plain, further north, so it is north-east.

Options that place Bihar to the south-east or Gujarat to the south-west or north-east reverse one of these directions.

Answer: C

The actual distance is about 3.05 km.

\[ \begin{aligned} 19.7 \times 155 &= 3053.5\ \text{m} \\ &\approx 3.05\ \text{km} \end{aligned} \]

3.10 km rounds 19.7 up to 20 cm, and 30.5 km and 31.00 km slip the decimal point by a factor of ten.

Answer: A

The abilities developed are (a), (b) and (c).

Map reading in primary EVS helps children understand the relative positions of places, directions, and the use of symbols and scale.

Drawing maps precisely to scale (d) is a cartographic skill beyond the primary stage; children make rough sketches and simple maps, not exact scale drawings.

Answer: B

The house at X is due south of the school.

The two east-west moves cancel: 75 m west from A to B and 75 m east from C to Y. The north moves add up: 125 m from X to A and 150 m from B to C, 275 m in all. So Y is 275 m due north of X, which means X is due south of Y.

'Due North' gives the direction of the school from the house, the reverse of what is asked. North-west and south-east would need an unbalanced east-west movement.
