Ok, here’s the question:(adsbygoogle = window.adsbygoogle || []).push({});

A motorist traveling at 89 km/hr is being chased by a police car at 115 km/hr. If the police car starts from 3.5 km back, how long does it take to catch the motorist? Leave time in hours.

Now I’m looking at this as a relative motion problem since there is no acceleration, therefore time should be equal to the distance between the cars, divided by the difference in the velocity between the two cars.

Therefor; t = (3.5 km) / [(115 km/hr) - (89 km/hr)]

Therefore; t = 0.13 hr

However it’s apparently wrong, so does anybody know what I’m doing wrong and how to fix it? :surprised Thanks
