Answer:
Given that a polynomial has a constant term and at least one other term what is the minimum number of possible zero values based on the rational zero test? a-0 b-2 c-3 d-4
Using the student id given above, a = 19 and b = 7
Average speed for the first 54 km = 48+a km/h
Plug a = 19
Average speed for the first 54 km = 48+19 = 67 km/h
Average speed for remaining 86 km = 43-b km/h where b = 7
Average speed = 36 km/h
Average speed of entire journey = total distance / total time taken
Time taken to cover 54 km = hr
Time take to cover 86 km = hr
Total time taken = 3.2 hours.
Total distance = 86+54= 140 km
Average speed of the entire trip = = 43.75 km/ h
