Let wind speed = x mph
when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x = 2 / t -------(1) where t is the time she took.
when riding with the wind we have
20 + x = 3 / t--------(2) adding equations (1) and (2):-
40 = 2/t + 3/t
40 = 5/t
t = 5/40 = 1/8 hr
x = 20 - 2 / 1/8 = 20 - 16 = 4
Wind speed was 4 mph Answer
Answer:
0.25
liter of red paint, 0.25 liter of blue paint,
and 4.5 centiliters of white paint.
Step-by-step explanation:
The answer would be the second one
C = 4900 + 175S
The graph will cross the y-axis at 4900 and show a slope of 175/1 . Good luck graphing. If you choose the right scale, the graph will be easier. Increment by by 500 on the yaxis and 25 on the x-axis.
