Question

Malia runs 5 miles in 1 hour. How many miles does she run in half an hour?

Answer 1

Hint: In this question we have been asked to find how many miles does Malia run in half an hour if the given information states that “she can run 5 miles in 1 hour”. For doing that we will calculate her speed using the formula mathematically given as $speed=\dfrac{\text{distance}}{\text{time}}$ .

Complete step by step solution:
Now considering from the question we have been asked to find how many miles does Malia run in half an hour if the given information states that “she can run 5 miles in 1 hour”.
For doing that we will use our basic concepts and calculate her speed using the formula mathematically given as $speed=\dfrac{\text{distance}}{\text{time}}$ .
Malia speed is given as $speed=\dfrac{5miles}{1hour}\Rightarrow 5miles/hour$ .
As we know her speed we can calculate her distance covered in a given time by multiplying the given time and speed with each other.
By doing this we will have
$\begin{align}
  & \text{distance=5miles/hour}\times \dfrac{1}{2}hour \\
 & \Rightarrow \text{distance=}2.5miles \\
\end{align}$

Hence we can conclude that Malia can run 2.5 miles in half an hour, given that if she can run 5 miles in 1 hour.

Note: During the process of answering questions of this type our concepts that we are applying should be clear and calculations that we are performing should be perfect. This is a very simple question and can be answered in a short span of time. Very few mistakes are possible in questions of this type. We should be careful while performing calculations. We can make a calculation mistake like $\dfrac{5}{2}=2.25$ and end up having a wrong conclusion.
