Question

The school Cafeteria sells 22 drinks every 10 minutes. Predict how many drinks the cafeteria will sell during the 45-minute lunch period.

Answer 1

The school cafeteria sells 22 drinks every 10 minutes, or 11 drinks every 5 min.

(22/10)/(2/2) =11/5

there are 45 min in a lunch period

45/5 = 9

multiply the 9 with 11

9 x 11 = 99

The cafeteria can sell 99 drinks in a 45 min period

hope this helps
