D= distance
t= time
s= speed
FORMULA
Distance= speed * time
STEP 1:
Find total distance
Jim's D + John's D= 3 miles
STEP 2:
Distance= (Jim's speed * time) + (John's speed * time)
D= 4t + 5t
3 miles= 9t
divide both sides by 9
3/9= t
reduce by 3
1/3 hour= t
STEP 3:
1 hour= 60 minutes
=1/3 * 60
=(60/3)
= 20 minutes
ANSWER: They will travel 20 minutes before they meet.

Answer:
Step-by-step explanation:
The smallest is 4 and since there has to be two fives, the two middle numbers are 5. The range 3 so that means the biggest number is 7. So the set is 4,5,5,7
To be a function every input value (x) can only have one output value (y)
On the graph there are 2 out put values for x = 2 so it is not a function.
The answer would be C.
Answer:
3x=y
3x-y=0
(y-75)+(X+25)=90
X+y=90+50
X+y=140
3x-y+X+y=0+140
4x=140
X=35(girls)
y=105(boys)
children were in the museum at first? *=35+105
<em>=140</em>
