Question

Jason took 6 hours to travel 540 km. For the first 140 km, he took 2 hours.

What was his average speed during the first two hours? ___ km/h
How much distance did he cover in the last four hours of his journey? ___ km
What was his average speed for the rest of the journey? ___ km/h

Answer 1

Answer: Average speed for the first two hours was 70 km/hr

Covered 400 km in the last four hours

Average speed for the rest of the journey was 100 km/hr

Explanation: 140 km / 2 hours = 70 km/hr

540 km - 140 km = 400 km remaining for the last four hours

400 km / 4 hours = 100 km/hr for the last four hours
