Question

Last year, 60% of runners who competed in the Labor Day race finished in 1 hour or less. There were 285 runners who finished the Labor Day race in 1 hour or less. How many runners competed in the Labor Day race?

Answer 1

Answer:

475 runners competed in the Labor Day race.

Step-by-step explanation:

Given:

Last year, 60% of runners who competed in the Labor Day race finished in 1 hour or less. There were 285 runners who finished the Labor Day race in 1 hour or less.

Now, to find the runners competed in the Labor Day race.

Let the runners competed in the Labor Day race be $x.$

Rate of runners who competed in the Labor Day race finished in 1 hour or less = 60%.

Number of runners who competed in the Labor Day race finished in 1 hour or less = 285.

Now, to get the runners competed in the Labor Day race we put an equation:

$60\%\ of\ x=285$

$\frac{60}{100} \times x=285$

$0.60x=285$

Dividing both sides by 0.60 we get:

$x=475.$

Therefore, 475 runners competed in the Labor Day race.
