Question

While standing in line to buy concert tickets, Kit moved 60 feet closer to the ticket window over a period of 30 minutes. At this rate, how many minutes will it take her to move the remaining 70 yards to the ticket window?

Accepted Answer

She moved 60 feet in 30 minutes, meaning her rate is 6030 = 2 feet per minute. She has 70 3 = 210 feet remaining, meaning she will need 2102 = 105 more minutes.
