Homework SourseIf a car traveled at an average speed of 80 kilometers per h
If a car traveled at an average speed of 80 kilometers per hour for twenty minutes, and then slowed to an average speed of 50 kilometers per hour over the next 15 minutes. How far would it travel in total?
Solution
Distance = Speed*Time
D = (80kmph)*[20mins] + [50kmph][15mins]
D = [80*20/60] + [50*15/60]
D = 80/3 + 25/2
D = 235/6 = 39.1 km
