Question

Jose runs 3 mikes in 28 minutes. At the same rate, how many miles would he run in 42 minutes?​

Answer 1

`4.5 \: miles`

Explanation:

`3 \: miles \: in \: 28 \: minutes.`

`x \: miles \: in \: 42 \: minutes.`

`28x=42 * 3`

`28x=126`

`(28x)/(28)=(126)/(28)`

`x=(9)/(2)`

Answer 2

`4.5 \: \: miles \\`

Explanation:

`3 \: \: miles = 28 \: \: min \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: x \: \: \: = 42 \: min`

use cross multiplication

`42 * 3 = 28 * x \\ 12 6 = 28x \\ (126)/(28) = (28x)/(28) \\ x = 4.5 \: \: miles`
