Ana's speed in miles per hour is [tex]7\frac{1}{2}[/tex]
Ana's speed in miles per hour can be determined by dividing the distance she ran by the time she ran. The time measurement that would be used would be hour instead of minutes because the question requests that the speed be determined in miles per hour
Speed = distance ÷ time
Distance = [tex]\frac{3}{4}[/tex]
Time = [tex]\frac{1}{10}[/tex]
Speed = [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{10}[/tex]
Speed = [tex]\frac{3}{4}[/tex] x 10 = [tex]\frac{15}{2}[/tex] = [tex]7\frac{1}{2}[/tex] miles per hour
In order to determine Ana's speed, divide the distance she ran by the time she ran.
