Answer:
[tex]108\frac{3}{4}[/tex] miles
Step-by-step explanation:
lets say Beth's family traveled x miles before stopping for gas. after lunch, they then traveled 3(x+ 65 1/4) more miles. so the total number of miles traveled is x + 65 1/4 + 3 (x + 65 1/4) or 4(x + 65 1/4), distribute to get4x+261. 4x+261= 372 since they traveled 372 miles that day. subtract 261 from both sides to get 111. divide by 4 to get x=111/4 or x= 108 3/4.
