Answer: 104 miles </h3>
=========================================================
Explanation:
x = number of miles Amy drove 2x = number of miles Jessica drove, since she drove twice the distance as Amy did Combine the two expressions: x+2x = 3x
The two girls traveled a total distance of 312 miles, so 3x = 312
Divide both sides by 3 to solve for x. You should get x = 104
Amy drove 104 miles and Jessica drove 2*104 = 208 miles
Check:
Amy + Jessica = 104 + 208 = 312
The answer is confirmed.
Answer:
Amy drove 104 miles
Step-by-step explanation:
let 'a' = miles Amy drove
let '2a' = miles Jessica drove
a + 2a = 312
3a = 312
a = 312/3
a = 104
2a = 208
Check: 104+208 should equal 312 and it does
