Question

In $10minutes$, a car with a speed $60km{h}^{-1}$ travels a distance of:

• A. $6km$
• B. $600km$
• C. $10km$
• D. $1km$

Answer 1

The correct option is C

$10km$

Explanation for the correct option::

(C): $10km$

Step 1: Given data and to find

Given a car having speed $60km{h}^{-1}$ and time is $10minutes$ we need to find the distance it covers.

Step 2: Formula used

$$\begin{gathered} \mathrm{Speed}=\frac{\mathrm{Distance}}{\mathrm{Time}} \\ \mathrm{Distance}=\mathrm{Speed}\times \mathrm{Time} \end{gathered}$$

Step 3: Finding distance

Here, given $10minutes$, converting into hours we get,

$$\begin{gathered} 1\mathrm{hour}=60\mathrm{minutes} \\ 10\mathrm{minutes}=\frac{10}{60}\mathrm{hours} \\ 10\mathrm{minutes}=\frac{1}{6}\mathrm{hours} \end{gathered}$$

Thus, substituting all the values in the formula used we get

$$\begin{gathered} \mathrm{Distance}=\mathrm{speed}\times \mathrm{time} \\ \mathrm{Distance}=60\times \frac{1}{6} \\ =\frac{60}{6}=10\mathrm{km} \end{gathered}$$

Therefore the car travels a distance of $10km.$
