Question 1 Report

A boy cycles continuously through a distance of 1.0 km in 5 minutes. Calculate his average speed

0.3ms^-1

3.3ms^-1

16.6ms^-1

20.0ms^-1

200.0ms^-1

Answer Details

The formula for calculating average speed is: average speed = distance traveled ÷ time taken In this question, the distance traveled by the boy is 1.0 km, and the time taken is 5 minutes or 5 × 60 = 300 seconds. Substituting these values into the formula: average speed = 1.0 km ÷ 300 seconds To convert km to meters, we multiply by 1000. average speed = 1000m ÷ 300 seconds Simplifying: average speed = 3.33 m/s Therefore, the boy's average speed is 3.33 ms^-1. So, the correct option is: 3.3ms^-1.
