Answer 1

Answer:

A and B start at the same time with speeds of 40 km/hour and 50 km/hour respectively.

If in covering the journey, A taken 15 minutes longer than B, the distance of the journey is :

Step-by-step explanation:

Suppose distance of journey = x km

Time taken by A to Cover x km = x/40 hours.

Time taken by B to Cover x km = x/50 hours.

x/40 - x/50  = 15/60  or  x/200= 15/60

x = (15 x 20)/6

x=50 km
