Year 8 Speed, Distance and Time Worksheet — Level 2 — Practice Set 3 — Answers

Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.

1.A car travels 142.5 km at an average speed of 95 km/h. How long does the trip take?

Answer: 1 hour 30 minutes

  1. time = distance ÷ speed = 142.5 ÷ 95
  2. = 1.5 h = 1 hour 30 minutes
2.A train travels at 45 km/h for 1 hour 15 minutes. How far does it travel?

Answer: 56.25 km

  1. time = 1.25 h
  2. distance = speed × time = 45 × 1.25
  3. = 56.25 km
3.A train travels at 55 km/h for 30 minutes. How far does it travel?

Answer: 27.5 km

  1. time = 0.5 h
  2. distance = speed × time = 55 × 0.5
  3. = 27.5 km
4.A train travels at 45 km/h for 45 minutes. How far does it travel?

Answer: 33.75 km

  1. time = 0.75 h
  2. distance = speed × time = 45 × 0.75
  3. = 33.75 km
5.A train travels at 115 km/h for 45 minutes. How far does it travel?

Answer: 86.25 km

  1. time = 0.75 h
  2. distance = speed × time = 115 × 0.75
  3. = 86.25 km
6.A car travels 225 km at an average speed of 75 km/h. How long does the trip take?

Answer: 3 hours

  1. time = distance ÷ speed = 225 ÷ 75
  2. = 3 h = 3 hours
7.A car travels 67.5 km at an average speed of 45 km/h. How long does the trip take?

Answer: 1 hour 30 minutes

  1. time = distance ÷ speed = 67.5 ÷ 45
  2. = 1.5 h = 1 hour 30 minutes
8.A train travels at 40 km/h for 1 hour 15 minutes. How far does it travel?

Answer: 50 km

  1. time = 1.25 h
  2. distance = speed × time = 40 × 1.25
  3. = 50 km
9.Ethan travels 28.75 km in 15 minutes. What is the average speed in km/h?

Answer: 115 km/h

  1. time = 0.25 h
  2. speed = distance ÷ time = 28.75 ÷ 0.25
  3. = 115 km/h
10.A train travels at 20 km/h for 1 hour 30 minutes. How far does it travel?

Answer: 30 km
