Question

13) Srikant runs at a speed of 35 km per hour
and completes a race in 16 minutes. It
Prasad's speed is 32 km per hour, in how
much time will he complete the race?​

Answer 1

Answer:

17.49 min.

Step-by-step explanation:

Srikant runs at the speed of 35 km/hour.

So, in 60 min Srikant runs 35 km. [Since 1 hour=60 min]

Srikant completes the race in 16 min.

Hence, we can find out the total distance of the race track in the method given below:

In 60 min Srikant runs 35 km.

In 1 min Srikant runs (35/60) km.

In 16 min Srikant runs (35/60) * 15 km.

                       =9.33 km

Therefore the total distance of the race track is 9.33 km.

Prasad runs at the speed of 32 km/hour.

So, to run 32 km Prasad takes 60 min.

   To run 1km Prasad takes (60/32) min.

   To run 9.33 km Prasad takes (60/32) * 9.33 min.

                              = 17.49 min.

Therefore Prasad will complete the race in 17.49 min.
