Question

Calculate Average Speed A train travels 230 km from City A to

City B in 3 hours. Then, the train travels 400 km from City B to City
C in 4 hours. Calculate the train's average speed for the entire trip.

Answer 1

90 km/hr

Explanation:

The average speed is the total distance / total time

Total distance = 230 + 400 km = 630 km

Total time = 3 hours + 4 hours = 7 hours

Average speed = 630 km / 7 hr = 90 km/hr
