37.5 mile per hour
112.5 miles
Explanation:rate = 60km per hour
1 mile = 1.6 kilometer
Let's convert:
[tex]\frac{60\operatorname{km}}{1\text{ hour}}\times\frac{1\text{ mile}}{1.6\operatorname{km}}[/tex][tex]\begin{gathered} \frac{60\operatorname{km}}{1\text{ hour}}\times\frac{1\text{ mile}}{1.6\operatorname{km}}\text{ km cancels out, we are left with mile per hour} \\ \text{= }\frac{60\text{ mile}}{1.6\text{ hour}} \\ =\text{ 37.5mile per hour} \end{gathered}[/tex]The car's rate in miles per hour is 37.5 mile per hour
In 1 hour, the car travels 37.5 mile
In 3 hours, the car will travel = 3 × 37.5miles
= 112.5 miles
In 3 hours, the car will travel 112.5 miles
