Question 1074705: When a van is drived without stopping it's speed is 54 km/h and when drived with stop place to place then its speed is 45 km/h then for what minutes van is stoped per hour? Answer by ikleyn(52884) (Show Source):
Had the van move at 54 km/h with NO stopping, it would spend = hours = 50 minutes to cover 45 kilometers.
But in reality it spent 1 hour to cover 45 kilometers.
It means that the van was stopped 10 minutes per hour.
Answer. Van was stopped 10 minutes per hour.
