Question
A car travels 300 km at a speed of 60 km/h and another
200 km at a speed of 80 km/h. Find the approximate average speed of the car for the entire journey.Solution
Total distance = 300 km + 200 km = 500 km Total time = 300 km / 60 km/h + 200 km / 80 km/h = 5 hours + 2.5 hours = 7.5 hours Average speed = Total distance / Total time = 500 km / 7.5 hours = 66.67 km/h or 68 km/h (approximately)
