Answer:
Step-by-step explanation:
2+9-18/3x2-10
Lets follow order of ops.
/, x, +, -
Divide first.
2 + 9 - (18/3) x 2 - 10
2+9-6x2-10
Now we multiply.
2+9-(6x2)-10
2+9-12-10
Add.
11-22
Now subtract.
11-22=-11

Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
