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?

remaining distance covered in time 105 min

Explanation:

Given data

Kit moved = 60 feet

period = 30 minutes

to find out

many minutes will it take

solution

we know in 30 min kit move 60 feet

so speed of moving is = distance/time

speed = 60/30

sped is 2 feet/min

so remaining distance cover 70 * 3 i. e 210 feet

remaining distance covered in time = remaining distance / speed

remaining distance covered in time = 210 / 2

remaining distance covered in time 105 min
