Question

Over the weekend Ella ran three times as many miles as Vera. Together they ran 24 miles. How many miles did Vera run?

Answer 1

`6\ miles`

Explanation:

Let

x------> number of miles Vera ran

y-----> number of miles Ella ran

we know that

`x+y=24` -----> equation A

`y=3x` -----> equation B

substitute equation B in equation A and solve for x

`x+(3x)=24`

`4x=24`

`x=6\ miles`
