word problem: it takes jake 10 hrs to mow a large lawn but it takes tyler 12 hrs. if they both mow the same lawn how long would it take to finish the job?

In each hour, Jake can mow 1/10 of the lawn, and Tyler can mow 1/12 of the lawn, so in x hours, working together, they can do x/10 + x/12 = 1 (whole lawn). So, just solve for x.
