Question 41

Step1: Calculate miles driven

Subtract start odometer from end odometer: $58857 - 58236 = 621$ miles.

Step2: Calculate miles left

Subtract miles driven from total trip: $1792 - 621 = 1171$ miles.

To find the rate of girls to boys, simplify the ratio $88:96$. Divide both by 8: $\frac{88}{8}:\frac{96}{8}=11:12$. This means there are 11 girls for every 12 boys.

Answer:

1,171 miles
