Answer: 16
Justification:
Given that there are only 3 data you must assume proportionality to solve this problem.
Proportionality is the equality of two ratios. In this case, one of the ratio have an unknown variable, and given that you have the other three values of the proportion you can calculate the unknown.
This is the proportion to solve:
5 baskets x
----------------- = ----------------
4 minutes 13 minutes
Now, solve for x:
x = 13 minutes * 5 baskets /4 minutes = 16.25 baskets
You have to round to the nearest whole number = 16 baskets.
