A person boarded Rajdhani train from New Delhi on 30 April 2022 and reached Bhubaneshwar on 01 May 2022. The train departed from New Delhi at 17:00 hours and reached Bhubaneshwar at 20:00 hrs on 01 May 2022. If the distance between New Delhi and Bhubaneshwar by train route is nearly 1701 km. The average speed of the train during this journey was :
Answer: B
The average speed was 63 km/h.
The train left at 17:00 on 30 April and arrived at 20:00 on 1 May:
\[ \begin{aligned} \text{time} &= 7 + 20 = 27\ \text{h} \\ \text{speed} &= \frac{1701}{27} = 63\ \text{km/h} \end{aligned} \]
The 7 hours run from 17:00 to midnight and the 20 hours from midnight to 20:00. 62.7 km/h and 63.3 km/h are what you get with a time slightly too long or too short, and 60 km/h does not come from 27 hours.
