Question

Terri's car gets 27 miles to the gallon and holds 13 gallons of gas. Using the following function, determine the maximum length of time Terri can drive her car on one tank of gas if she were to drive at a constant rate of 39 miles per hour.

In this function d(t) represents the distance driven, v represents the rate at which Terri is driving, and t represents the time she drives for.

Answer 1

4.33 hours
B.
9 hours
C.
1.44 hours
D.
27 hours

Answer 2

we dont know the rate of the driving tho

do we?

Answer 3

We do know actually

Answer 4

okay,it says that it takes a gallon to travel 27 miles

Answer 5

But the car can hold up to 13 gallons

Answer 6

351

Answer 7

351 miles for the 13 gallons

Answer 8

yeah,that's right

Answer 9

alright,we already know the total distance can be driven
There is another information given to us,saying that the rate of driving is 39 miles per hour

Answer 10

\(d(t)=351~miles\)

Answer 11

\(v=39~miles~per~Hour\)

Answer 12

Using the formula given,now u can find the time

Answer 13

\(d(t)=v\times~t\)

Answer 14

sub the values into the formula and solve for t

Answer 15

\(351~Miles=39~Miles~per~Hour\times~t\)

Answer 16

9 hours deet

Answer 17

yep,that's correct!
