Question

A train travels 67 kilometers in 1 hours, and then 81 kilometers in 5 hours. What is its average speed?

Answer 1

Average speed = (total distance) / (time to cover the distance)

Total distance = (67 km + 81 km) = 148 km

Time to cover the distance = (1 hr + 5 hr) = 6 hr

Average speed = (148 km) / (6 hr) = (24 and 2/3) km/hr
