Yumi and Juan pick up litter along the highway at the same rate. Yumi picks up litter for 3 miles and takes 2 hours longer than Juan, who picks up litter for 2 miles. If Juan spent x hours picking up litter, the following equation models
the situation
XX+2
How long did Yumi spend picking up litter?
1 hour 20 minutes
O 3 hours 20 minutes
4 hours
6 hours

its 6 hours

6 hours

Step-by-step explanation:

Let's say that the number of hours that Yumi picked litter for is y.

You know that since Yumi picked litter for 2 hours more than Juan, y=x+2.

y=3m

x=2m

Subtract the second equation from the first:

y-x=m

Substitute:

x+2-x=m

2=m

This means that it takes 2 hours per mile of litter. Multiplying this by the 3 miles that Yumi walked makes a total of 6 hours. Hope this helps!
