London's family took a road trip to the Grand Canyon. London fell asleep 61% of the way through the trip. If London fell asleep after they had travelled 305 miles, what was the total length of the trip?

782.05 miles.

Step-by-step explanation: Percentage is a ratio expressed as fraction of 100, in other words, 61% is represented as or 0.61.

London slept 61% of the journey, so it means he was awake for 39% of the journey. Now the total trip is or 1, so the relationship will be

0.39 ---- 305 miles

   1   ----- x

x = 782.05

The total length of the trip was 782.05 miles.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
