Answer:
333.67 miles
Step-by-step explanation:
She drives her car 91 mi on 3 gal of gas
That’s 91 mi = 3 gal
How many miles can she drive on 11 gal of gas .
Let the mile she can drive by 11 gal of gas be A
At the same rate ,
91 mi = 3 gall
A mi = 11 gal
Cross multiply
A x 3 = 91 x 11
A x 3 = 1001
Divide both sides by 3
A x 3/3 = 1001/3
A = 333.67 miles
At the same rate she’ll drive 333.67 miles on 11 gal of gas
Compute the derivative of 
at 
- this will be the tangent vector - then normalize it by dividing it by its magnitude to get the unit tangent vector 
.
