If the line is moving about 4 feet every 15 minutes, then a person will need about 3 hours to reach 50-foot line from the back to the front. It's because:
50 / 4 = 12,5 (that's how many quarters of an hour one needs to move 50 feet)
12,5 * 15 = 187,5 (that's how long it will take in minutes)
187,5 min = 3h 7min 30 sec
Approx. - 3h
50 / 4 = 12,5 (that's how many quarters of an hour one needs to move 50 feet)
12,5 * 15 = 187,5 (that's how long it will take in minutes)
187,5 min = 3h 7min 30 sec
Approx. - 3h
set it up in fractions and cross multiply:
15/4=x/50
4x=750
x=187.5 minutes which converts to 3.125
Your answer is 3 hours (:
