Given

Required

Determine the number of miles driven on the highway and on the city

Represent the gallons used on highway with h and on city with c.

So, we have:

---- gallons used

and

--- distance travelled

In the first equation, make c the subject

Substitute 10 - h for c in the second equation

Open bracket

Collect like terms

Make h the subject

Substitute 5 for h in

If on the highway, he travels 31 miles per gallon, then his distance on the highway is:

If in the highway, he travels 26 miles per gallon, then his distance on the highway is:

p = 6s
