Question

If a car travels 60 km in an hour, how far will it travel in 2 hours?

Answer 1

Hint: To find the distance travelled by the car in 2 hours, first of all let this distance be equal to d. Now, to find this distance, we are going to use the method of cross multiplication. So, the distance travelled by the car in 2 hours will be equal to 60 multiplied by 2.

Complete step by step solution:
In this question, we are given that a car travels $60Km$ distance in an hour and we are supposed to find the distance that the car will travel in $2$ hours.
For finding this distance, we are going to use the method of cross multiplication. First of all, let the distance travelled by the car in $2$ hours be $d$.
Now,
$$\begin{gathered} 1hr=60km \\ 2hr=d \end{gathered}$$
So, therefore, the distance travelled by car in 2 hours ($d$) is given by multiplying 60 with 2 and dividing with 1. Therefore, we get
$$\begin{gathered} \Rightarrow d={\displaystyle \frac{60\times 2}{1}} \\ \Rightarrow d=120km \end{gathered}$$
Hence, if the car travels $60Km$ distance in $1$ hour, it will travel $120Km$ distance in $2$ hours.

Note:
Here, we can also solve this question using the formula of the speed. The formula of speed is given by
$\text{Speed}={\displaystyle \frac{\text{Distance}}{\text{Time}}}$
Here, the speed of the car is 60 Km/hrs. and we need to find the distance travelled in 2 hours. So, therefore
$$\begin{gathered} \Rightarrow \text{Distance}=\text{Speed}\times \text{Time} \\ \Rightarrow \text{Distance}=60\times 2=120km \end{gathered}$$
