Answer 1

Given : A train takes 12 hours and 20 minutes to reach city B from city at an average speed of 25 m/s.

To find : The distance between the cities A and B ?

Solution :

The average speed is 25 m/s.

The time taken by train is 12 hours and 20 minutes.

Convert into seconds,

1 hour=60minutes1 hour=60 minutes

12hour}=12×60 minutes 12 hour=12×60 minutes

12 hour=720 minutes12 hour=720 minutes

Total time is 720 minute +20 minute = 740 minutes

Now, 1minute}=60 seconds1 minute=60 seconds

740 minute=740times 60 seconds740 minute=740×60 seconds

740 minute=44400 seconds 740 minute=44400 seconds

So, time is 44400 seconds.

The distance formula is given by

Distance=Speed×Time

Distance}=25× 44400Distance=25×44400

Distance}=1110000\ mDistance=1110000 m

Therefore, the distance between the cities A and B is 1110000 m.
