A car traveled 60 km in 2 hours, 84 km in the next 1 hour, and then 68km in 2 hours before reaching its destination. What was the cars average speed?

The formula for average speed is calculated by finding the ratio of the total distance covered by the object to the time taken to cover that distance. We calculate as follows:

average speed = (total distance) / total time

average speed = 60 + 84 + 68 / 2+1+2 = 42.4 km/h
