To determine the speed, we will divide the total distance covered by the total time spent traveling.

$speed=distance\div time$ $speed=412.5miles\div7.5hrs$

<em>Note that 7 1/2 is just equal to 7.5.</em>

<em />

Divide the numbers above and the answer is:

$speed=55miles\text{ }per\text{ }hour$

Answer:

Ivan was driving at a constant speed of 55 miles per hour.

How do I find the inverse of this problem?

raketka [301]

$\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the Concept of the Inverse of real function.

Let's consider here, g(n) = y ,

so we get as,

$y = \sqrt[3]{ \frac{n - 1}{2} }$

no, cubing the power both side we get as,

${y}^{3} = \frac{n - 1}{2}$

now,

$2 {y}^{3} = n - 1$

so finally, we get as,

$n = 2 {y}^{3} + 1$

hence,here, n = inverse of the g(n) function.

so,

g^-1 (n) = 2y^3+1.
