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:
[tex]=1 + \dfrac{\text{seconds}}{60}\\\\=1 + \dfrac{24}{60}\\\\=1.4\text{ minutes}[/tex]
Formula:
[tex]\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
Putting values, we get.
[tex]45 = \dfrac{\text{Distance}}{1.4}\\\\\text{Distance} = 45\times 1.4 = 63\text{ m}[/tex]
Thus, Alex swims for 63 m in 1 minute and 24 seconds.
Using the equation that relates velocity, distance, and time, it is found that he swims 63m in 1 minute and 24 seconds.
---------------------------------
Velocity is given by distance divided by time, thus:
[tex]v = \frac{d}{t}[/tex]
---------------------------------
- Velocity of 45 meters per minute, thus, [tex]v = 45[/tex].
- Time of 1 minute and 24 seconds, thus [tex]t = 1 + \frac{24}{60} = 1 + 0.4 = 1.4[/tex]
Solving for the distance, we find how far he swims, thus:
[tex]v = \frac{d}{t}[/tex]
[tex]45 = \frac{d}{1.4}[/tex]
[tex]d = 45 \times 1.4[/tex]
[tex]d = 63[/tex]
He swims 63m in 1 minute and 24 seconds.
