Question

You can now 800 square feet of lawn in 15 minutes at this rate how many minutes will it take you to mow a lawn that measures 6000 square feet?
Part A write a proportion to represent the problem. Use M to represent the number of minutes. Explain your reasoning.

Part B solve the proportion you wrote in part A. Then use it to answer the problem. Show your work.

Answer 1

Ok so assuming you don't get tired and the rate stays the same
rate=amountwork/timeitdonein

rate=800/15

euals
6000/time

800/15=6000/time
simlify for ease
160/3=6000/time
multiply both sides by 3time
160time=18000
divide both sides by 160
time=112.5

means 112.5 minutes or 1hour, 52 minutes, 30 seconds

A. 800/15=6000/t or
15/800=t/6000

B. solved, 112.5 minutes
