Diatance travelled by her= 350 miles
amount of time taken by her to travel 350 miles= 7 hrs 30 mins
=450 mins
average speed travelled by her to the nearest tenth of a mile per hour= 450*60/100
=270/10
=27
therefore he travelled 27 miles to the nearest tenth of a mile per hour.

Here is how we get the answer....
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
