Question

Martin prepared 6 kilograms of dough after working 3 hours. How many hours did Martin work, if he prepared 14 kilograms of dough? Solve using unit rates

Answer 1

6kg/3hours is his rate.

to find how much he made per hour, you divide by 3.

2kg/hour

now multiply that rate by 7, which gives you 14kg.

therefore, he worked 7 hours to prepare 14kg of dough.
