Question
Learning Goal:
Two-segment travel. Practice the relationship
between speed - time - ditance in various ways
A car is making a trip in a total time of 110 min.
During the first 40 min its average speed is 30
mph
Transcribed Image Text:Learning Goal: Two-segment travel. Practice the relationship between speed - time - ditance in various ways A car is making a trip in a total time of 110 min. During the first 40 min its average speed is 30 mph
1 mile = 1609 m. ! hour = 60 minutes. I minute = 60 seconds.
Note: these basic conversion factors will be given to you in exams if needed.
Part A-What average speed of the rest of the trip is needed if the car's overall average speed of the entire trip is
51.82 mph ? Keep two digits after the decimal point.
Be careful: in general we CAN'T write Aveage speed of entire trip = (1/2) (1st segment speed + 2nd segment speed)
