A good way to approach this problem would be to set up a proportion by using the following thought process:
(i) Rate is usually written as distance per unit time OR d/t. So, we can set up the first part of this problem as 737miles/11hours.
(ii) Now, we are told that the rate is the same, so this 737miles/11hours must be equal to something, and for a proportion to work, we need to make sure we align the same units in the numerator as well as in the denominator. In this case, our proportion would look like this:
737miles/11hours = d (the distance we are solving for)/13hours
(iii) We can cross-multiply and solve for d (our distance):
11(d) = 9,581
d = 871 miles
