Question

A cafeteria sells 30 drinks every 15 minutes. Predict whether at the rate that rate the cafeteria will sell at least 90 drinks every hour

Answer 1

no

Explanation:

60min/15mln=4

so 4*30=120 and it does not = to 90

30:15 =2:1 but 90:60=3:2

Answer 2

Answer: yes

Step-by-step explanation:

90/30 = 3

15x3 = 45

45 minutes is less than an hour (60 minutes). therefore as they sell 90 drinks every 45 minutes they sell at least 120 drinks an hour (30x4))
