715 miles / 11 hours = 65 mph
845 miles / 65 mph = 13 hours
It would take 13 hours to drive 845 miles.
To solve the problem, what you must do is a system of two equations with two Ingonites that describe the problem.
Let:
x = number of shirt buttons.
y = number of buttons on jackets.
Writing the system:
36x + 42y = 842
6x + 7y = 137
We observe that the system is linearly dependent, therefore, it can not be solved.
However, the solution is to solve the system of two equations with two unknowns.
In order to solve it, the system must be linearly independent.
Perimeter = 2 × π × r
Perimeter = 2 × 3.14 × 9
Perimeter = 56.52
Perimeter = 56.52 ÷ 2
Perimeter = 28.26
The perimeter of a semicircle with a radius of 9mm is 28.26
General formula to be used:

F = future worth; P = present worth, i = annual interest, n = years

F = $329.395.)
P = $1.45 *I doubt the 1212 years. I think that is a typo error. Nevertheless, just substitute the correct number of years to determine P :)
If u and v are perpendicular, then their dot product is zero:

Solve for p :
