Year 9 Speed, Distance and Time Worksheet — Level 3 — Practice Set 4 — Answers

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

1.Jack travels 75 km in 1 hour 15 minutes. What is the average speed in km/h?

Answer: 60 km/h

  1. time = 1.25 h
  2. speed = distance ÷ time = 75 ÷ 1.25
  3. = 60 km/h
2.A train travels at 60 km/h for 40 minutes. How far does it travel?

Answer: 40 km

  1. time = 0.6667 h
  2. distance = speed × time = 60 × 0.6667
  3. = 40 km
3.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
4.A car travels 200 km at an average speed of 120 km/h. How long does the trip take?

Answer: 1 hour 40 minutes

  1. time = distance ÷ speed = 200 ÷ 120
  2. = 1.6667 h = 1 hour 40 minutes
5.A car travels 10 km at an average speed of 30 km/h. How long does the trip take?

Answer: 20 minutes

  1. time = distance ÷ speed = 10 ÷ 30
  2. = 0.3333 h = 20 minutes
6.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
7.A train travels at 60 km/h for 1 hour 40 minutes. How far does it travel?

Answer: 100 km

  1. time = 1.6667 h
  2. distance = speed × time = 60 × 1.6667
  3. = 100 km
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

  1. time = distance ÷ speed = 75 ÷ 60
  2. = 1.25 h = 1 hour 15 minutes
9.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
10.A train travels at 90 km/h for 1 hour 30 minutes. How far does it travel?

Answer: 135 km
