Alex swims at an average speed of 45m/min. How far does he swim in 1 minute and 24 seconds?

aksik [14]

Answer:

63 m

Step-by-step explanation:

We are given the following in the question:

Average speed of swimming = 45 m/min

Time = 1 minute 24 seconds

Converting time into minutes:

$=1 + \dfrac{\text{seconds}}{60}\\\\=1 + \dfrac{24}{60}\\\\=1.4\text{ minutes}$

Formula:

$\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}$

Putting values, we get.

$45 = \dfrac{\text{Distance}}{1.4}\\\\\text{Distance} = 45\times 1.4 = 63\text{ m}$

Thus, Alex swims for 63 m in 1 minute and 24 seconds.
