Oversized 53431

Behind the vehicle with an oversized load, which moves at an average speed of 16 km/h, they sent a second escort vehicle 2.5 hours later, which travels at an average speed of 70 km/h. At what time and at what distance does this vehicle reach the oversized load?

Correct answer:

t =  0.7407 h
s =  51.8519 km

Step-by-step explanation:

v1=16 km/h T=2.5 h v2=70 km/h  s1=s2=s  v1 (t+T)=v2 t 16 (t+2.5)=70 t  54t=40  t=5440=0.74074074  t=27200.740741=0.7407 h
s=v2 t=70 0.7407=27140051.8519 km   Verifying Solution:  s1=v1 (t+T)=16 (0.7407+2.5)=27140051.8519 km s1=s
