Question
A man drives at a steady speed of 75 km/h for 4 hours,
followed by another stretch of 3 hours at a consistent speed of 40 km/h. What is his average speed over the entire journey?Solution
Total distance travelled by the man = 75 x 4 + 40 x 3 = 300 + 120 = 420 km Total time taken = 4 + 3 = 7 hours So, average speed = total distance travelled ÷ total time taken = 420 ÷ 7 = 60 km/h
