Car travel

A passenger car traveling at a speed of 60 km/h arrived from place A to place B one and a half hours earlier than a truck traveling at 40 km/h. How far apart are placed A and B, and how long did the car travel?

Final Answer:

s =  180 km
t =  3 h

Step-by-step explanation:

v1=60 km/h v2=40 km/h  s = v1 t s = v2(t+1.5)  v1 t=v2(t+1.5) 60 t=40(t+1.5)  60 t=40 (t+1.5)  20t=60  t=2060=3  t=3  s=v1 t=60 3=180 km
