Question

a train takes 120 minutes to complete a journey of 40 km without stopping in between. calculate the speed of train.​

Answer 1

Explanation:

Speed = Distance

         ____________

                Time

We usually take time in hours so therefore we'll convert 120 minutes in hours

1 hour = 60 mins

120/ 60 = 2 hours

Speed = 40 km / 2 hours

Speed = 20 km/h

Therefore, speed of train is 20 km/h

May the answer helps you!!

Answer 2

Given: Distance covered by the train=40km

             Time taken by the train= 120 minutes

To find The speed of the train

Solution: The given question is based on speed, time, and distance, and this kind of numerical we solve in physics and mathematics. We can get the derived quantity 'speed' by the division of two fundamental quantities distance and time.

Now from above, Distance covered by the train=40km

                              Time taken by the train= 120 minutes

                                                                       =2hours [∵1hour=60 minutes]

∴ The speed of the train

= Distance covered by the train/Time taken by the train

= 40/2 km/hr

= 20km/hr

Hence the speed of the train is 20km /hr.
