Question

June walked 3.1 fewer miles in April than in

Answer 1

Answer:

March: 28 miles, April: 24.9 miles, May: 30.1 miles

Step-by-step explanation:

Equations

Let's call x the amount of miles walked by June in March. We know she walked 3.1 fewer miles in April than in  March. The miles for April are

$x-3.1$

She walked 5.2 more miles in May  than in April. So in May she walked

$x-3.1+5.2=x+2.1$

The total of miles walked is expressed by

$x+x-3.1+x+2.1=3x-1$

This expression is equal to 83 miles, thus

$3x-1=83$

Solving for x

$x=84/3=28$

That is the distance in miled walked in March. In April she walked

$x-3.1=28-3.1=24.9\ miles$

And in May, she walked

$24.9+5.2=30.1\ miles$
