The bus travels the distance s = 40 km from the city to the village in time t = 1 hour, making several stops. The average speed of a bus between bus stops is u = 60 km / h. How much of the total time is the bus at a stop?
The given tasks: S (distance from the city to the village, the path covered by the bus) = 40 km; t1 (duration of movement with stops) = 1 hour; Vav. (average speed of this bus between stops) = 60 km / h.
The duration of the bus stops can be determined by the formula: t = t1 – t2 = t1 – S / Vav.
Let’s calculate: t = 1 – 40/60 = 0.333 h or 20 min.
Answer: The duration of all bus stops is 20 minutes.
