Question

Two boys a and b start at the same time to ride from ghaziabad to meerut which is 60km away. A travels 4km and hour slower than b who reaches meerut and at once turns back to meet a 12km away from meerut. Find the speed of



a.

Answer 1

Answer:

Step-by-step explanation:

Let speed of a is X

Then speed of b is X+4

Total distance covered by b=60+12=72

Total distance covered by a =60-12=48

Time of a and b is same

So 72/X+4=48\x

72x=192+48x

24x=192x=8
