Question

A train begins a journey from a station and
travels 60 km in a time of 20 minutes. What is the
average speed of the train?
3.0 ms-1
5.0 ms-1
50 ms-1
60 ms-1​

Answer 1

Answer:

50ms-1

Explanation:

AS= Total Distance/Total Time Taken

Total Distance = 60km = 60000m

Total Time Taken= 20 minutes = 20×60 sec = 1200sec

60000m/1200sec = 50ms-1

Total distance covered by train= 60 km or 60000 m

Total time taken = 20 mins or 20×60 seconds

Average speed

$= \frac{Distance }{ time}$

$= \frac{60000}{20 \times 60}$

$= 50$

So, Answer - 50 m/s
