Question

A man covers a certain distance in 2 hours 45 minutes. when he walks at the rate 4km/hr. how much time will take to cover the same distance if he runs at a speed 6.5km/hr

Answer 1

Let the distance be 'x'
Time = 2 hrs. 45mins
= 2.75 hrs
Speed = 4 km/hr
Speed = distance/ time
4 =x/2.75
X = 11 km
With same distance , different speed we have to find time & let the time be 't'
Speed = distance/ time
6.5 = 11/t
6.5t = 11
t = 11/6.5
t = 1.69 hr
I hope this would be help for you
