Question

A copy machine can print 480 copies every 4 minutes. For each question, explain your reasoning.

– PART A: How many copies can it print in 10 minutes?
– PART B: A teacher printed 720 copies. How long did it take to print?

Answer 1

800 because 8 mins = 480 times 2 = 560, 2 mins = 480/2 = 240, 10 mins = 560 + 240 = 800

Answer 2

Part A =1200 copies

Part B = 6 hours

Explanation:

Part A is 480 divided by 4 = 120 and then 120 times 10 = 1200

Part B is 720 divided by 120 = 6
