Question

two groups collect litter along the side of the road. it takes each group 5 minutes to clean a 2 yd section. how long would it take to clean up 2 miles

Answer 1

each group take 5 mins to do 2yds
2 groups so in 5 mins, 4 yards gets cleaned

how many yards per mile is 1760

2 miles=2*1760=3520

find how many times of the 5 mins they have to clean (remember 4 yds per 5 mins)
3520/4=880
that means 880 times 5mins=4400mins=73hrs and 20mins
