Alden walked 2 miles in 3/4 hours .kira walked 1 3/4 miles in 30 minutes? who walked at a faster rate?

Kira did because by the time she walked for 45 minutes, she would be above 2 miles

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
