Harun and Kuna competed in a 200-m race. Harun ran at a constant speed of 5 m/s. Kuna ran at a constant speed of 8 m/s. (a) Find the time Kuna took to reach the finishing line. (b) How far was Harun from Kuna when Kuna reached the finishing line?​

Answer 1

(a) To find the time Kuna took to reach the finishing line, we need to know the distance of the race. Let's assume it is 200 meters, since it is not specified in the problem.

Kuna's speed = 8 m/s
Distance of race = 200 m

Time = Distance / Speed
Time taken by Kuna = 200 / 8
Time taken by Kuna = 25 seconds

Therefore, Kuna took 25 seconds to reach the finishing line.

(b) We can use the formula Distance = Speed x Time to find how far Harun was from Kuna when Kuna reached the finishing line.

Harun's speed = 5 m/s
Time taken by Kuna = 25 seconds

Distance covered by Harun in 25 seconds = Speed x Time
Distance covered by Harun = 5 x 25
Distance covered by Harun = 125 meters

Therefore, Harun was 125 meters away from Kuna when Kuna reached the finishing line.
