Question

A boy takes 8 minutes of reach his school by car. If the school is 4.8 km from his house, his average speed ​

Answer 1

Answer:

average speed = 10 m/s or 36 km/hr

Explanation:

Given that a boy takes 8 minutes of reach his school by car and the school is 4.8 km from his house.

We need to find out the average speed of the boy.

Average speed is defined total distance travelled per unit time.

Average speed = (Total distance travelled)/(Time taken)

Where total distance travelled by the boy is 4.8 km and time taken is 8 min.

1 km = 1000 m

4.8 km = 4800 m

1 min = 60 sec

8 min = 480 sec

Substitute the values,

Average speed = 4800/480

Average speed = 10

Therefore, the average speed of the boy is 10 m/s or 36 km/hr.
