If the train travels 18 mph you just have to divide 270 by 18 and that would be your answer.
So 270/18 = 15 which means it would take the train 15 hours to travel 270 miles.
Answer:
60 2/3
Step-by-step explanation:
The population of Oak Forest is increasing at a rate of 4% per year.
Increase rate, r = 4%
Current population, P = 39,410
time, t = 3 years
Population after 3 years will be:

Population after 3 years will be 44331
Answer:
dy/dx= 7- 3x^-1/2
when X=1
dy/dx = 4
as it is a tangent M1=M2=4
now,
at gradient 4 and point (1,1)
equation of curve is ,
y-y1= m(x-x1)
or, y-1=4(x-1)
or, y-1=4x-4
or, y-4x= -3
or, 4x-y=3
