Question

To save fuel to avoid air pollution and for good health two person A andB ride a bicycle for a distance of 12km to reach their office. As the cycleing speed is 2km/h more than that of A B, takes 30 min less than that of A to reach the office. Find the time taken by AandB to reach the office

Answer 1

Step-by-step explanation:

Distance , s= 12km

Speed , v = 2km /hr .

Time , t = ? (to be calculated )

We know that , v = s/t

So , t = s/v

=> t = 12/ 2 hr

=> t = 6 hr = 6×30 min = 180 min

As B takes 30 min less than that of A , time taken by B is 180- 30 min = 150 min

Time taken by A is 180 minutes while that of B is 150 minutes .
