Question

A girl runs 15 km in 30 minutes. What is her speed in kmph?

• A. 5 kmph
• B. 15 kmph
• C. 30 kmph
• D. 40 kmph

Answer 1

The correct option is C 30 kmph

Given, t = 30 min
and distance covered = 15 km
Converting into hours, we get
$t=30\times \frac{1}{60}=0.5h$
Using the formula, $speed=\frac{distance}{time}$
we get,
Speed $=\frac{15}{0.5}=30kmph$
