1.A train travels at 30 km/h for 1 hour 40 minutes. How far does it travel?

Answer: 50 km

  1. time = 1.6667 h
  2. distance = speed × time = 30 × 1.6667
  3. = 50 km
2.A train travels at 30 km/h for 45 minutes. How far does it travel?

Answer: 22.5 km

  1. time = 0.75 h
  2. distance = speed × time = 30 × 0.75
  3. = 22.5 km
3.A car travels 50 km at an average speed of 30 km/h. How long does the trip take?

Answer: 1 hour 40 minutes

  1. time = distance ÷ speed = 50 ÷ 30
  2. = 1.6667 h = 1 hour 40 minutes
4.A train travels at 30 km/h for 2 hours 15 minutes. How far does it travel?

Answer: 67.5 km

  1. time = 2.25 h
  2. distance = speed × time = 30 × 2.25
  3. = 67.5 km
5.A car travels 37.5 km at an average speed of 30 km/h. How long does the trip take?

  1. time = distance ÷ speed = 37.5 ÷ 30
  2. = 1.25 h = 1 hour 15 minutes
6.Amelia travels 150 km in 1 hour 15 minutes. What is the average speed in km/h?

Answer: 120 km/h

  1. time = 1.25 h

  3. = 120 km/h
7.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
8.A car travels 75 km at an average speed of 60 km/h. How long does the trip take?

Answer: 1 hour 15 minutes
