Johnny mows 6 yards in 1 hour, and he has 21 yards to mow. How long will it take him?

2 answers:

This is a proportion equation. 6 yards in 1 hour is 21 yards to x hours.

x=hours it takes to mow 21 yards

1) Set up your proportion: 6 yards / 1 hour = 21 yards / x hours
2) Now you cross multiply. (6*x)=(1*21)
3) 6x=21
4) Divide both sides by 6
5) x=3.5

So Johnny can mow 21 yards in 3.5 hours.

Hope this helps! :)

Answer:

40 + 2r

Step-by-step explanation:

Well an hour has 60 minutes.

So 60 x 1/30 = 60/30 = 2 minutes for each person that didn't get into the job

60 x 1/3 = 60/3 = 20 minutes for the people that made it into the job.

20 x 2 = 40 minutes in total for the people that made it into the job.

We don't know how much people got rejected so:

The answer is

40 + 2r
