Answer: 90 km/h

  1. time = 2.25 h
  2. speed = distance ÷ time = 202.5 ÷ 2.25
  3. = 90 km/h
2.A car travels 135 km at an average speed of 90 km/h. How long does the trip take?

Answer: 1 hour 30 minutes

  1. time = distance ÷ speed = 135 ÷ 90
  2. = 1.5 h = 1 hour 30 minutes
3.Ava travels 200 km in 1 hour 40 minutes. What is the average speed in km/h?

Answer: 120 km/h

  1. time = 1.6667 h
