Question

Answer 1

Answer:

7.5 miles per hour

Step-by-step explanation:

Given: Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate

To find: speed in miles per hour

Solution:

Distance travelled by Kayla = $\frac{3}{4}$ mile

Time = $\frac{1}{10}$ hour

To find the speed in miles per hour, use the following formula:

Speed = Distance ÷ Time = $\frac{\frac{3}{4} }{\frac{1}{10} }=\frac{3}{4}(10)=7.5$ miles per hour
