Simultaneously 6997

Two boys train to run on a 400 m closed track. They both run simultaneously from the same starting track in the same direction. Boy A runs at a constant speed of 5 m/s, and Boy B runs at a constant speed of 3 m/s. At what time does Boy A overtake Boy B for the first time? How far will the boys run in this time?

Correct answer:

t =  200 s
s1 =  1000 m
s2 =  600 m

Step-by-step explanation:

5t = 400 + 3t

5·t = 400 + 3·t

2t = 400

t = 400/2 = 200

t = 200

Our simple equation calculator calculates it.
s1=5 t=5 200=1000 m
s2=3 t=3 200=600 m
