Answer:170
Step-by-step explanation:
If 25% is 85 then multiply 25% by 2 to get 50% and 85 by 2 to get 179
Answer:
1,000-25x=400+75x
Step-by-step explanation:
x=amount of days it'll take
1,000-25x=400+75x
We have a direct variation. Distance, D, varies directly as time, t.
So D = Kt where K is the constant. In this case, speed. So D = Kt is our constant of variation.
If D = 150 miles and t = 4 hours
Then we have 150 = K (4)
K = 150/4 = 37.5. The constant of variation is 37.5.
If you keep traveling at a constant speed K = 37.5 and D = 200. We have
200 = 37.5 * t
t = 200/37.5 = 5.333 hours.
