Travels 20483

When and where will the two cars that drove at the same time from cities A and B 90 km apart if the car from city A travels at a speed of 75 km/h and the car from city B at a speed of 60 km/h meet?

Correct answer:

t =  0.6667 h
s1 =  50 km

Step-by-step explanation:

v1=75 km/h v2=60 km/h  90=v1 t+v2 t 90=75 t+60 t  135t=90  t=13590=0.66666667  t=320.666667=0.6667 h
s1=v1 t=75 0.6667=50 km
