Problema Solution
Aja and Emilie were riding bikes. They knew they could ride 3 miles in 20 minutes. How far could they travel in 45 minutes?
Answer provided by our tutors
Let 'x' represent the number of miles they could travel in 45 minutes. The ratio of 'known' and 'unknown' is solved:
3/20=x/45
x=6.75
So they could travel 6 3/4 miles.
