Answer:
The answer to your question is 166 mi/h
Step-by-step explanation:
Data
ve = rate eastbound train
vw = rate westbound train = ve - 14
distance = d = 900 mi
time = t = 5 h
Formula
v = 
Substitution and simplification

Now, substitute this value in the equation of vw
vw = 180 - 14
Result
vw = 166 mi/h
421906 can be partitioned to 400000 + 20000 + 1000 + 900 + 00 + 6
The number 421906 is in between 400000 and 500000, but it's closer to 400000, so rounding to the nearest hundred thousand gives 400000
The number 421906 is in between 421000 and 422000, but it's closer to 422000, so the nearest thousand is 422000
Answer:
(7, 11)
Step-by-step explanation:
If a line segment has endpoints at A(
) and B(
), the coordinates of the midpoint O(x, y) of the segment AB is given by the formula:

Given the midpoint M(3, 5) of the segment CD with the coordinates of C at (-1, -1). Let the coordinates of D be at (
). Hence:

Hence the coordinates of D is at (7, 11)
W = -15.4
