17 km/h
Average speed = distance ÷ time = 34 ÷ 2 = 17 km/h.
8. A vehicle travels 420 km in 5 hours. Find its average speed.
84 km/h
Average speed = distance ÷ time = 420 ÷ 5 = 84 km/h.
9. A vehicle travels 51 km in 1 hours. Find its average speed.
51 km/h
Average speed = distance ÷ time = 51 ÷ 1 = 51 km/h.
10. A vehicle travels 3 km in 1 hours. Find its average speed.
3 km/h
Average speed = distance ÷ time = 3 ÷ 1 = 3 km/h.
11. A vehicle travels 64 km in 4 hours. Find its average speed.
16 km/h
Average speed = distance ÷ time = 64 ÷ 4 = 16 km/h.
12. A vehicle travels 102 km in 6 hours. Find its average speed.
17 km/h
Average speed = distance ÷ time = 102 ÷ 6 = 17 km/h.
