1.A car travels 20 km at an average speed of 60 km/h. How long does the trip take?

Answer: 20 minutes

  1. time = distance ÷ speed = 20 ÷ 60
  2. = 0.3333 h = 20 minutes
2.A train travels at 120 km/h for 2 hours 15 minutes. How far does it travel?

Answer: 270 km

  1. time = 2.25 h
  2. distance = speed × time = 120 × 2.25
  3. = 270 km
3.A car travels 80 km at an average speed of 120 km/h. How long does the trip take?

Answer: 40 minutes

  1. time = distance ÷ speed = 80 ÷ 120
  2. = 0.6667 h = 40 minutes
4.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
5.Olivia 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
6.Emma travels 22.5 km in 45 minutes. What is the average speed in km/h?

Answer: 30 km/h

  1. time = 0.75 h
  2. speed = distance ÷ time = 22.5 ÷ 0.75
  3. = 30 km/h
7.Cooper travels 10 km in 20 minutes. What is the average speed in km/h?

Answer: 30 km/h

  1. time = 0.3333 h
  2. speed = distance ÷ time = 10 ÷ 0.3333
  3. = 30 km/h
