Passenger 2690

The express train set off from city A to city B at an average speed of 100 km/h. At the same time, a passenger train departed from city B to city A. The trains met after 90 minutes. Calculate the average speed of a passenger train if the distance between the seats is 240 km.

Correct answer:

v =  60 km/h

Step-by-step explanation:

v1=100 km/h t=90 min h=90:60  h=1.5 h s=240 km  s = v t  s=(v1+v) t 240=(100+v) 1.5  1.5v=90  v=1.590=60  v=60=60 km/h
