Farmer Janet can plant 5 feet of carrots in 15 minutes while her daughter Amy can plant 15 feet of carrots in half an hour. Which farmer plants carrots more quickly? Why? What is each farmer's rate in carrots per hour?

Answer:

Amy is faster

Janet: 20 ft/h; Amy: 30 ft/h

Explanation:

To find the rate in feet per hour, divide feet by hours.

Janet's rate = (5 ft)/(15/60 h) = 20 ft/h

Amy's rate = (15 ft)/(1/2 h) = 30 ft/h

Amy plants more quickly, because 30 > 20.
