(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 45.0 min at 55.0 km/h, 17.0 min at 65 km/h, and 60.0 min at 30.0 km/h, and spends 55.0 min eating lunch and buying gas.

(a) Determine the average speed for the trip.

km/h

(b) Determine the distance between the initial and final cities along this route.

km

2. Relevant equations

I am having considerable difficulty getting started can you go cover the basics as intrinsically as possible this is my first corse in physics and only my third corse in science (I took a year of basic biology and chemistry) I have been given three formulas on average motion and instantaneous motion do these apply? I also have covered the velocity, acceleration, and change in position formula .. any help would be greatly appreciated so that I may understand and complete the rest of my homework on my own thank you in advance

3. The attempt at a solution

So far I have no attempted solutions I don't fully understand the question being asked to be frank. I tried taking the average of all the speeds but the we bite where I submit homework told me it was incorrect .. I have a feeling I first have to find the distance traveled how would that be done and do I need to convert units? again any help would be greatly appreciated thank you!
