Question

1. if allan swims at an average speed of 2 metres per second, how long will it take him to complete a 200 metre race?

Explanation:

Step1: Recall the formula for time

The formula relating speed ($v$), distance ($d$), and time ($t$) is $t = \frac{d}{v}$.

Step2: Identify the given values

We know that the speed $v = 2$ metres per second and the distance $d = 200$ metres.

Step3: Substitute the values into the formula

Substitute $d = 200$ and $v = 2$ into the formula $t = \frac{d}{v}$. So, $t = \frac{200}{2}$.

Step4: Calculate the result

$\frac{200}{2}= 100$.

Answer:

It will take Allan 100 seconds to complete the 200 - metre race.
