Question

Aiden's family took a road trip to Niagrara Falls. Aiden fell asleep 18% of the

way through the trip. If Aiden fell asleep after they had travelled 72 miles,
what was the total length of the trip?

A) 400 miles
B) 360 miles
C) 320 miles
D) 300 miles

Answer 1

By setting up a proportion where 18% of the trip equals 72 miles, and solving for the total distance, we find that the entire trip to Niagara Falls was 400 miles long.

Step-by-step explanation:

To determine the total length of the trip to Niagara Falls, we need to find what distance corresponds to 100% of the journey when 18% is equivalent to 72 miles.

First, we express the percentage as a decimal by dividing it by 100, which gives us 0.18. Then, we set up the proportion:

0.18 (total distance) = 72 miles

To find the total distance, we divide 72 miles by 0.18:

Total distance = 72 miles / 0.18

After performing the calculation, we find that the total distance is 400 miles. Therefore, the correct answer to Aiden's road trip length is option A) 400 miles.
