Answer 1

Given : Walking at 3/4 th of his usual speed, a man is 1 hour late.

To Find : usual travel time.

Solution:

Lets assume that

Usual Speed  =   4S   km/hr

Usual Time    =  T    hr

Distance = Speed x Time

=> Distance = 4S * T

=> Distance = 4ST  km

Walking at 3/4 th of his usual speed

=> Speed = (3/4)4S = 3S km/Hr

Distance = 4ST  km

Time taken  = 4ST /3S   = 4T/3 hr

4T/3  = T  + 1

=> 4T = 3T + 3

=> T  = 3  hrs

his usual travel time. = 3 Hrs
