Problema Solution
Which derived unit is appropriate for the following situation?
Within 4 seconds, the child rode his bicycle 11 feet.
Answer provided by our tutors
The unit that is intuitively best is "miles per hour", hence convert seconds to hours and feet to miles:
(11/5280)/(4/(60*60))
1.875 = 1 7/8
So 1 7/8 miles per hour would describe how fast the child rode his bicycle.
