A person takes a trip, driving with a constant speed of 99.0km/h except for a 22.0-min rest stop. The person's average speed is 73.1km/h.
(a) How much time is spent on the trip?
(b) How far does the person travel?
Driving speed
Average speed ,
22 min stop means
---------
Time spent on trip =Time spent on driving +time spent on resting
Speed =Distance/time
Distance =Speed *time
Total distance driven =Driving speed* time spent on driving
-----------
Average Speed =Total Distance/Total time
(a)ANSWER:
=====================
(b) How far does the person travel?
