Answer:
100 miles
Step-by-step explanation:
Relative Speed: 60+40=100 mph
you can think that one train is stationary,another one is 100 mph
so one hour before the train pass each other，the distance is 100 miles
Answer:
The answer is B
Step-by-step explanation:
You add up all the numbers which should be 600 and divide by the total amount numbers used.
600/15=40.
<span>= 49567/1000
</span>rite the decimal number as a fraction
(over 1)
49.567 = 49.567 / 1
Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's
Numerator (N)
N = 49.567 × 10 × 10 × 10 = 49567
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000
N / D = 49567 / 1000
Simplifying our fraction

Sum of adjacent angles on a straight line is 180°
-------------------------------------------------------------------------
∠ABD + ∠CBD = 180°
(2x + 7) + (5x - 2) = 180
2x + 7 + 5x - 2 = 180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 25
------------------------------------------------------------------------
Answer: x = 25
