Question

Two groups collected litter along the side of the road it takes each group 5 minuites to clean up a 200 yard section how long does it take to clean up 2 miles

Answer 1

This is dividing 
So 1 mile has 1760 yards so in total 
2 miles = 3520 yards and it takes 5 minutes to clean up 200 yards (We divide)
3520 ÷ 200 = 17.6 ( Now we multiply)
17.6 x 5 = 88 minutes or ( 1 hour and 22 minutes)
