Detailed Explanation
The total distance traveled by both monorails can be computed by adding the distance traveled by the south monorail and the distance traveled by the south monorail:
total distance = distance south monorail + distance north monorail
Solve for distance traveled by each monorail using the formula distance = speed x time
distance traveled by south monorail = 65 x 4 = 260 miles
distance traveled by north monorail = 55 x 4 = 220 miles
total distance traveled by the 2 monorails = 260 + 220 = 480 miles
