The Average speed is 17.4 mph.
The average speed is calculated by dividing the total distance travelled by the total amount of motion time.
The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.
Average speed = Distance travelled/ Time taken
Given:
Distance = 5 4/5 = 29/5 miles
Time= 1/3 hours
So, Average speed = Distance travelled/ Time taken
Average speed= 29/5 x 3/1
= 87/5
= 17.4 mph
Hence, the Average speed is 17.4 mph.
