Darla drives at a constant speed of 45 miles per hour. If she drives for y miles and it takes her x hours, write the two-variabl
e equation to represent the number of miles Darla can drive in x hours.
1 answer:
Answer:
y = 45x miles
Step-by-step explanation:
Speed is the rate of change of distance with time. Mathematically,
speed = distance/time
Given that Darla travels at a constant speed of 45 miles per hour and for y miles, it takes her x hours then
45 = y/x
multiply both sides by x
45x = y
then the number of miles (y) Darla can drive in x hours
y = 45x (in miles)

Answer:
$14.80
Step-by-step explanation:
I'm assuming you meant to put 3.20 since $320 a mile would be ridiculous.
C(n)=2.00+3.20n
If n = 4 miles we have:
C(4)=2+3.20(4)
C(4)=2+12.80
C(4)=14.80
So the cost of the taxi is $14.80.
