[tex]\text{This question is asking us which expression could be used to solve}\\\text{for the amount of miles the second car is from the first}\\\\\text{We know that they both drove for 5 hours}\\\\\text{We also know the distance in which they were going}\\\\\text{So you would need to multiply both mph by 5 to get your total distance,}\\\text{then you would subtract them to get the distance apart}\\\\\text{This makes c the correct answer, since you're multiplying each mph and}\\[/tex]
[tex]\text{subtracting to get your answer}\\\\\boxed{C) (55 \cdot 5)-(40\cdot5)}[/tex]
