Question

1. It takes Keimon 36 minutes to ride his car 28 miles. At this rate, how longwill it take him to ride 38 miles? (YOUR ANSWER MUST BE IN HOURS)

Answer 1

it is given keimon travels 28 miles in 36 minutes

so its speed is = distance/ time

= 28 / 36

= 7/9 miles per minute

the time to travel 38 miles will be = distance/ speed

`=(38)/((7)/(9))=(38*9)/(7)=(342)/(7)`

so the time is 342/7 minutes

now we will convert it into hours

60 minutes = 1 hours

1 minute = 1/60 hours

342/7 minutes =

`\begin{gathered} =(1)/(60)*(342)/(7) \\ =0.81 \end{gathered}`

it will take 0.81 hours to ride 38 miles.
