Jake and travel the distance of 175 miles and 5 hours at what rate was he driving

It is very important to carefully look at all the important information's that are already given in the question. Based on those given information's the answer to the question can be easily deduced.
The amount of distance covered by Jake in 5 hours = 175 miles
Then
The amount of distance covered by Jake in 1 hour = (175/5) * 1 miles
                                                                                 = 35 * 1 miles
                                                                                 = 35 miles
So from the above deduction we can easily conclude that the unit rate of Jake is 35 miles per hour. I hope there is no complication about the procedure and it is easy for you to understand.

If you would like to know the rate that he was driving, you can calculate this using the following steps:

175 miles ... 5 hours
x miles = ? ...1 hour

175 * 1 = 5 * x
175 = 5 * x    /5
x = 175/5
x = 35 miles

The correct result would be 35 miles per hour.
