On the road from Moscow to the suburban area S = 75, a passenger of the electric train spends t = 1 hour 10 minutes.

On the road from Moscow to the suburban area S = 75, a passenger of the electric train spends t = 1 hour 10 minutes. The average speed of the train is v = 72 km / h. How long do the stops take?

These tasks: S (distance from Moscow to the summer cottage) = 75 km; t (time spent by the passenger) = 1 hour 10 minutes (1.167 hours); V (average speed of the train) = 72 km / h.

1) Determine the time of movement of the train without stops: t1 = S / V = 75/72 = 1.042 hours.

2) Let’s calculate the duration of the train stops along the entire route: t2 = t – t1 = 1.167 – 1.042 = 0.125 h = 7.5 minutes.

Answer: The train stops took 7.5 minutes.
