Dema's truck gets 32 mpg on the highway and 18 mpg in the city. The amount of gas he uses A (in gal) is given by A=118c+132h, wh
Zigmanuir [339]

We conclude that he drove 176 miles on the highway

<h3>how many highway miles did he drive?</h3>

Here we have the equation:

A = (1/18)*c + (1/32)*h

Where A is the consumption in gallons of gas, c is the number of miles driven in the city and h is the number of miles driven in the highway.

Here we know that:

A = 8 gallons of gas.

c = 45 miles

Replacing that in the above equation, we can find the value of h.

8 =  (1/18)*45 + (1/32)*h

8 - (1/18)*45 = (1/32)*h

32*(8 - (1/18)*45) = h = 176

We conclude that he drove 176 miles on the highway
