Question

anonymous · Answer

X is the length of the trip. X(4/7) = 120km is what you know. To find out the total trip, multiply 120km by the inverse of 4/7, which is 7/4, to get x by itself, leaving you with the length of the trip. Simply take this number and subtract it by the length traveled (120km) and you will have your answer for km remaining.

To simplify = X(4/7) = 120km
X (4/7) (7/4) = 120km (7/4)
X = 210km (Length of the trip)
210km - 120km = 90km (length remaining)
