A suspect in a high speed chase enters I-8 Eastbound at 85 miles per hour. 16 minutes later a highway patrolman enters I-8 Eastbound at the same location at 93 miles per hour. How long until the officer catches up to the suspect?
The model is \(\displaystyle d=rt\). The suspect has a 16 minute head start. The equation for the distance traveled by the suspect is \(\displaystyle d=85(t + 16)\). The highway patrolman has traveled \(\displaystyle d=93 t\). To catch the suspect the distances traveled must be equal. This gives the equation is \(\displaystyle 85 t + 1360=93 t\). Solving gives that it will take \(\displaystyle 170\) minutes to catch the suspect.
