The given equation is


d=0.15t

d is the distance in miles

t is the time in seconds

b. We need to find the distance in 30 seconds

Then substitute t by 30 in the equation


d=0.15*30

The zero in 30 we move the decimal point 1 place to right then


\begin{gathered} d=1.5*3 \\ d=4.5\text{ miles} \end{gathered}

It will travel 4.5 miles in 30 seconds

c. We need to find the time to travel 12.75 miles

Then substitute d in the equation by 12.75


12.75=0.15t

Divide 12.75 by 0.15 to find t


t=(12.75)/(0.15)

The decimal point up will cancel the decimal point down


\begin{gathered} t=(1275)/(15) \\ t=85 \end{gathered}

It will take 85 seconds to travel 12.75 miles
