Question

Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate what is her speed in miles per hour

Answer 1

7.5 miles per hour

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 =
`(3)/(4)` mile

Time =
`(1)/(10)` hour

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

Speed = Distance ÷ Time =
`((3)/(4) )/((1)/(10) )=(3)/(4)(10)=7.5` miles per hour
