Question

In a 500 metre race b gives a start of 160 the ratio of the speed of a and b 2 is to 3 who wins and by how much

Answer 1

Answer:

20 METER

Explanation:

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
