A bus leaving a bus stop accelerates at 0.8 metre per second square for 5 s and then travels at a constant speed for 2 minutes before slowing down uniformly at 0.4 metre per second square to come to rest at the next bus stop. The total distance travelled by the bus is:

10feet apart then both

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
