$3 \frac{3}{4} = \frac{15}{4} miles$


$\frac{3}{4 } \times 60 = 45mins$



so,

$\frac{ \frac{15}{4} }{45} = \frac{15}{4} \times \frac{1}{45} = \frac{1}{12} miles \: per \: hour$


Hope it helps you

Answer 2

Do 3.75÷.75=5 

You will end up getting 5, which is 5 miles per hour.

Hope this helped!!
