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: x ≤ 950
Step-by-step explanation:
5,225.00÷5.50
= 950
Answer:
X= Negative 2/3 or -0.6
Step-by-step explanation:
here you go
You want to get x on one side so you divide both sides by 7 and 35/7 = 5
