Question

A and B ran a race of 1600 meters. The ratio of their speed is 3:4. If B gives A a start of 120 meters and still manages to win the race, find the difference in the distance covered by A and B when B touches the finishing line

Plz give the step by step solution

Answer 1

Step-by-step explanation:

20 meter

Distance covered by A in the race is 500 - 140 = 360 m

If his speed is 3x, then time taken by him = distance / speed (i.e 360/3x)

This is the time when A crosses the finish line.

Now let us see how far B has reached with his speed of 4 x in this time.

Distance covered by B = speed X time (i.e 4x X 360/3x)

which gives 480 m.

That means he is 20 m behind the finish line when A has already reached the finish liine.
