a train travels 99 kilometers in 3 hours, and then 80 kilometers in 5 hours. What is it’s average speed?
1 answer:
Average speed = (total distance covered) / (time to cover the distance)
Total distance covered = (99km + 80km) = 179 km
Time to cover the distance = 8 hours
Average speed = (179km / 8hours)
Average speed = 22.375 km/hour
