W.I.K

- At one location it takes him 5 hours to cut the entire lawn with the push Mower 

- Takes 70 minutes with the powerful riding mower 

- After 90% of the lawn was cut using the powerful riding mower the remainder was cut using the push mower 

- How many minutes did it take to cut the lawn? 

Since it takes 70 minutes to mow the lawn with the powerful riding mower and it cleared 90% of cutting the lawn we need to multiply 90% with 70 to see how much minutes it took with the powerful mower 

90% <-- change to a decimal 

0.9x70 = 63 

--------------

Now for the push mowers, it takes about 5 hours just to mow the lawn, and 90% was already mowed with the Powerful Riding mower so we have to change it into minutes by multiplying 60 minutes with 5 hours

5x60= 300 

We have to put that into minute to fit that 10% 

So multiply 10% and 300

10% <-- change to decimal 

0.10x300 = 30 

So it takes 30 minutes to mow the lawn with the push mower
