Answer:
0.5hrs
Step-by-step explanation:
Let the speed downhill be
,
Speed uphill is
. We are told than speed uphill is
the speed on flat ground. Therefore the speed on level ground will be
.
From this info, we can obtain the actual speed,
on level ground as:

speed, distance and time have the relation
so to obtain time to cover 45miles:

Hence it takes 0.5hrs to cover 45miles on flat ground.
Answer:
Domain : all real numbers
Step-by-step explanation:
The domain is the input values
What values can x be?
X can be any real number
Domain : all real numbers
Y is the output and x is the input. The given statement is output is 11 more than the output (x) so the function rule is y=x+11
