You can put this solution on YOUR website! Ron can make as many pizzas in 30 minutes as Jess can make in 40 minutes. How long iwll it take to amekt eh same number if they both work?
doing a certain number of pizzas is one job
1/2 hour Ron completes 1 job
so in 1 hour he does 2 jobs
2/3 hour jess takes for one job
in 1 hour he does 3/2 jobs
they both put to gether do 3/2 +2 jobs in 1 hour
=7/2 jobs in 1 hour
for 1 job they take 2/7 hours
=2/7 *60 minutes
