Question

In $12minutes$ a car whose speed is $35km{h}^{-1}$, travels a distance of:

• A. $7km$
• B. $14km$
• C. $3.5km$
• D. $28km$

Answer 1

The correct option is A

$7km$

Step 1: Given data

Speed = $35km{h}^{-1}$

Time = $12minutes$

Conversation minutes to hours: According to the question time is given 12 minutes and we know that $1hours=60min.$

Therefore, 12 minutes will be equal to $\frac{12}{60}=0.2hours$

Step 2: Finding distance

As we know that, $Dis\tan ce=speed\times time$

Substituting the given values in the formula, we get

$$\begin{gathered} dis\tan ce=speed\times time \\ =35\times 0.2 \\ =7km \end{gathered}$$

Therefore, the car covers a distance of $7km$.

Hence, option (A) is the correct answer.
