Question

Salma takes $15$ minutes from her house to reach her school on a bicycle. If the bicycle has a speed of $2m/s$, calculate the distance between her house and the school.

Answer 1

Step 1: Given data

Time taken by Salma (t) = $15$ minutes = $15\times 60s=900s$

Speed of bicycle (v) = $2m/s$

Step 2: Formula used

$Dis\tan ce=v\times t$, where v is the speed and t is the time taken.

Step 3: Calculate the distance between Salma's house and her school

On substituting the given values in the formula, we get:

$$\begin{gathered} Dis\tan ce=2\times 900 \\ =1800m \end{gathered}$$

Thus, the distance between Salma's house and the school is $1800m$ or $1.8km$.
