Harun and Kuna completed on a 250-m race. Harun ran at a speed of 6 m/s. Kuna dan at a speed of 8 m/s. If they started at the same time then the distance of Kuna from Harun when Kuna reached the finishing line....?

Answer 1

The faster runner finishes first. Kuna will finish first.
So Kuna finished first and the time was
distance = rate x time
250 m = 8 m/s x time
time = 250/8 = 31.25 s

How far has Harun run in that time?
distance = rate x time
d = 6 m/s x 31.25 x = 187.5 m
The separation is 250 - 187.5 = ? m
