A truck travelling east at 18.8 m/s is 1.56 km ahead of a car also travelling east, at
25.5 m/s. Assuming both speeds remain constant, how long will it take for the car
to pull even with the truck?​

Respuesta :

Answer:

at 25.5    S = 25.5 * t

at 18.8      S = 18.8 t + 1560 m   since this truck has 1560 m lead

25.5 * t = 18.8 t + 1560

t = 1560  m / 6.7 m/sec  = 233 sec
