What we are saying here is 136 students represent the rest of the students which is 100% minus 15% or 136 represents 85%. All we need to do ( there are several ways but I prefer this one) divide 136 by 85 then multiply by 100 to find answer which is 160
Her school is 2/3 miles away
2/3=4/6miles
So we need to find out how long it will take for her to run home from school...
School=4/6 miles
In 1 minutes she can run 1/6 miles
1min=1/6miles
In 2 minutes she can run 1/6+1/6 miles (1/6+1/6=2/6)
2min=2/6miles
3min=3/6miles
4min=4/6miles
It will take Erica 4 minutes to run 4/6 miles, so it'll take her 4 minutes to get home.
