A train travels 77 kilometers in 1 hour, and the 66 kilometers in 1 hour. What is the average speed?

Respuesta :

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

Total distance = (77km + 66km) = 143 kilometers

Time to cover the distance = 2 hours

Average speed = (143 km) / (2 hours) = 71.5 km per hour
