Question

11. The distance formula is d = rt, where d is the distance, r is the rate, and t is the time.a. Rewrite the equation to isolater.r = d/tb. Brad drove from Athens to Atlanta in 1.5 hours, 72 miles away, before he flew out forKansas City. What was his rate of speed in miles per hours

Answer 1

`\begin{gathered} d=r* t \\ (d)/(t)=(r* t)/(t) \\ \\ r=(d)/(t) \end{gathered}`

B. we just replace the vlues of t=1.5 and d=72

`\begin{gathered} r=(72)/(1.5) \\ \\ r=48(m)/(h) \end{gathered}`

the rate of speed is 48 miles per hour
