Answer:

17.67 mpg

Step-by-step explanation:

The fuel efficiency is given by :

$\eta=1.437+0.541\times s$

We need to find the fuel efficiency for a speed of 30 mph

Put the value of s equals 30 mph in the above equation.

$\eta=1.437+0.541\times 30\\\\\eta=17.67\ mpg$

So, the required fuel efficiency is equal to 17.67 mpg.
