Answer:
29 Minutes
Step-by-step explanation:
The original speed is given in miles per hour (like a car), but the answer is asking for miles per minute, so we must convert the speed into miles per minute first. To do this, we set up this equation: which equals
. We can then divide the desired number of miles by the speed in miles per minute. Here is the eqaution for this
. The miles cancel and you are just left with 29.1 minutes after you divide 4.9 by 0.168333333. Hope this helps!
Recall the polynomial remainder theorem: if is a factor of some polynomial
, then the remainder upon dividing
by
is
.
Let and
. The remainder left from dividing
by
is
If we subtract 5 from both sides, we'd get a "remainder" of 0, which suggests that we have to add -5 to to make
a factor.
