1.A car travels 45 km at an average speed of 30 km/h. How long does the trip take?

Answer: 1 hour 30 minutes

  1. time = distance ÷ speed = 45 ÷ 30
  2. = 1.5 h = 1 hour 30 minutes
2.A car travels 60 km at an average speed of 90 km/h. How long does the trip take?

Answer: 40 minutes

  1. time = distance ÷ speed = 60 ÷ 90
  2. = 0.6667 h = 40 minutes
3.A car travels 202.5 km at an average speed of 90 km/h. How long does the trip take?

Answer: 2 hours 15 minutes

  1. time = distance ÷ speed = 202.5 ÷ 90
  2. = 2.25 h = 2 hours 15 minutes
4.Isla travels 100 km in 1 hour 40 minutes. What is the average speed in km/h?

Answer: 60 km/h

  1. time = 1.6667 h

  3. = 60 km/h
5.A train travels at 60 km/h for 50 minutes. How far does it travel?

Answer: 50 km

  1. time = 0.8333 h
  2. distance = speed × time = 60 × 0.8333
  3. = 50 km
6.Oliver travels 60 km in 40 minutes. What is the average speed in km/h?

Answer: 90 km/h

  1. time = 0.6667 h
  2. speed = distance ÷ time = 60 ÷ 0.6667
  3. = 90 km/h
7.Isla travels 40 km in 40 minutes. What is the average speed in km/h?

Answer: 60 km/h

  1. time = 0.6667 h
  2. speed = distance ÷ time = 40 ÷ 0.6667
  3. = 60 km/h
8.A car travels 10 km at an average speed of 30 km/h. How long does the trip take?
