Question

Jessa completed a 50-mile bicycle race in 4 hours. After the race, she realized that the air pressure in her tires was low, which slowed her down by an average of 2 miles per hour. She wants to solve theequation below to find r, her average speed in miles per hour with properly inflated tires,4(r - 2) = 50

Answer 1

`\begin{gathered} 4(r-2)=50 \\ 4r-8=50 \\ 4r=58 \\ r=(58)/(4)=14.5 \end{gathered}`
