A boy cycles continuously through a distance of 1.0km in 5 minutes. Calculate his average speed.
A
0.3m/s
B
16.6m/s
C
20.0m/s
D
3.3m/s
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
Average speed = \(\frac{\text{total distance}}{\total time taken}}\)
d = 1. 0km ⇒ 1000m
t = 5minutes ⇒ 5 x 60 = 300 seconds
Average speed = \(\frac{1000}{300}\) = 3.3m/s
