Question

A roofing company claims they can haul away 755.2 hectograms of shingles every 90 minutes for trash. If they worked for 39 hours in a week, how many kilograms of shingles can they take to the trash?

Answer 1

Answer:

The roofing company can take out 196.352kg of shingles.

Step-by-step explanation:

• First, work out how many 90 minutes are in 39 hours:

       39 x 60 = 2340 minutes total

       2340 ÷ 90 = 26

• Then, multiply this by 755.2 to work out how much hectograms of trash is taken out.

       26 x 755.2 = 19635.2 hectograms of trash

• Finally, divide this by 10 to work out how many kilograms this is:

        19635.2 ÷ 10 = 196.352kg
