Question

10.
a student walks 2 km in 30 minutes, what is the students average speed in km/h
my answer is _____________________ (please use the correct units)

Explanation:

Step1: Convert minutes to hours

30 minutes is $\frac{30}{60} = 0.5$ hours.

Step2: Calculate average speed

Average speed formula is $v=\frac{d}{t}$, where $d = 2$ km and $t = 0.5$ h. So $v=\frac{2}{0.5}=4$ km/h.

Answer:

4 km/h
