## Homework Statement

A car traveling 93 km/h is 250 m behind a truck traveling 81 km/h.

How long will it take the car to reach the truck (in seconds)?

## Homework Equations

d=tv

## The Attempt at a Solution

d

_{c}= 93t

d

_{t}= 81t

d

_{c}= d

_{t}+ 250

93t = 81t + 250

12t = 250

t = 250/12

t = 20.83h = 75,000sec

The online homework website (I just started AP Physics 1) says that is the incorrect answer. Where did I go wrong? Do I need to use a different equation(s)?

Thank you in advance for helping.
