Answer:
wilma is 22.5 mph
fred is 25.5 mph
Step-by-step explanation:
Time:40 minutes, or 2/3 hours
Speed:
Fred:x+3
Wilma: x
Distance:32 miles
2/3(x+x+3)=32
2/3(2x+3)=32
1 1/3x+2=32
4/3x=30
x=22.5
wilma is 22.5 mph
fred is 22.5+3= 25.5 mph
D is the answer.
If f(x) or y = 2x, the inverse is x = 2y or y=x/2 which is not f(x).
So using the equation distance = velocity * time
we get distance/velocity = time
60 MPH: 290/60 = 4.83333 Hours
60 MPH: 290/70 = 4.1429 Hours
Difference between them:
4.8333 - 4.1429 = 0.69 Hours, then multiply that by 60 and you get
41 Minutes.
Hope this helped!
*psst it would help if you gave me brainliest answer, I'm close to ranking up :) Thanks!
