The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below:

Car A:
y = 52x + 70

Car B:
y = 54x + 56

After how many hours will the two cars be at the same distance from their starting point and what will that distance be?

6 hours, 420 miles
6 hours, 434 miles
7 hours, 420 miles
7 hours, 434 miles

When you answer this can you explain

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
