Sam delivers 3 newspapers in 5 minutes. If he continues at this rate, how long will it take him to deliver 45 newspapers?
2 answers:
Answer:
It will take him 75 minutes.
Step-by-step explanation:
Rule of three / cross-multiplication:
3 newspapers require 5 min
45 newspapers require x min
x = (45 / 3) * 5
x = 15 * 5
x = 75 min
Answer:
75 minutes
Step-by-step explanation:
3 newspapers = 5 minutes
45 newspapers = x minutes
45/3 = 15
3 x 15= 45 newspapers
5 x 15 = 75 minutes
Another way:
x= minutes
45/3= x/5
15=x/5
75=x
