Question

in the hare tortoise race the hare ran for 2min at a speed of 7.5km/hr slept for 56min and again ran for 2min at a speed of 7.5km/hr.Find the average speed of the hare in the race?

Answer 1

Hey.

Here is the answer.

Distance travelled in the first 2min

= speed × time

= 7.5 kmph × (2/60 hr)

= 15/60 km

Distance travelled in next 56 min

= 0 km as he was sleeping

Again distance travelled in last 2 min

= 7.5kmph × (2/60 hr)

= 15/60 km

So, total distance travelled = (15+0+15) /60

= 30/60 km

= 0.5 km

Total time taken= 2 +56 +2 min = 60 m

= 1 hr

So, as average speed

= total distance travelled / total time taken

So v avg= 0.5km / 1 hr

= 0.5 km/hr is the average speed of the hare.

Thanks.
