Answer:
44.71 mi/h
11.17 mi
Explanation:
To express the velocity in the S.I. you use the following equality:
[tex]1km=0.621\ mi[/tex]
then, by replacing you obtain:
[tex]72\frac{km}{h}*\frac{0.621\ mi}{1km}=44.71\frac{mi}{h}[/tex]
When the car has traveled while 15 minutes you have:
[tex]x=vt=(44.71\frac{mi}{h})(15min)\\\\15min*\frac{1\ h}{60\ min}=0.25\ h\\\\x=(44.71\frac{mi}{h})(0.25\ h)=11.17mi[/tex]
