Answer 1

Given:

In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.

His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour

To find:

What is Mila's average swimming speed?

Solution:

The distance swam by Logan = 750 m

The distance swam by Mila = $\frac{2}{3}$ of Logan's distance = $\frac{2}{3} \times 750 = 2 \times 250 = 500$

The time taken by Mila to swim 500 m = $\frac{1}{4}$ of an hour = $\frac{1}{4}\times 60 = 15\:minutes$ .... [since 1 hr = 60 mins]

We know the formula as:

$\boxed{\bold{Speed = \frac{Distance}{Time} }}$

Now, substituting the values in the formula above to find the speed of swimming of Mila,

The average swimming speed of Mila = $\frac{500\:m}{15\:min} = 33.34\:m/min$

Thus, Mila's average swimming speed is → 34.44 m/min.
