Starting from 1.5 miles away, a car drives toward a speed checkpoint and then passes it. The car travels at a constant rate of 53 miles per hour. The distance of the car from the checkpoint is given by d = 1.5 – 53t. At what times is the car 0.1 miles from the checkpoint? Calculate your answer in seconds.

Okay, it's multiple choice, so I guess the answers gave away my second question. I was asking *you*. Have you written out an equation?

d=1.5−53t where d is in miles and t is in hours. first divide both sides by 53 to get: d53=1.553−t this can be split into two portions: (1) for t <= 1.5/53 hours we can write: d53=1.553−t t=1.5−d53 (2) for t > 1.5/53 hours we can write: d53=−(1.553−t)=t−1.553 t=1.5+d53

Of course you don't. You haven't written out an equation yourself. It makes perfect sense that you don't understand it.
