90% of runners who started a marathon completed it. Of those, 30% are men. If 270 men completed the marathon, then how many tota
il63 [147K]

Given- 90% of runner completed the marathon.

out of which 30% are man.

To proof -  let the total number of runner be y.

the men completed the marathon be 30% of the 90%.

thus we have

30% of 90% of y = 270

\frac{30}{100}×\frac{90}{100}×y = 270

now solving the above equation

we get

\\y=\frac{270\times 100\times 100}{90\times 30}

Thus solving the equation

y = 1000

Thus the total runners of men who completed marathon be 1000.

Hence proved

Kyle entered to run in a 5K (5 kilometers) race. He wants to figure out how many miles are in the race. If there are 1000 meters
tekilochka [14]

Answer:

3.11 miles

Step-by-step explanation:

Hello!

First we have to get the distance into meters

The problem says there are 5 kilometers in a race and 1000 meters in a kilometer so 5 kilometers is 5000 meters

Now we turn the meters into miles

It says a mile is about 1609.34 so we can divide the amount of meters by how many meters are in a mile

5000/1609.34 = 3.106

Round to the nearest tenth

3.106 ⇒ 3.11

The answer is 3.11 miles

Hope this helps!
