Answer:
first do:
60mph * 4 hours= 240mi
Let D = the distance the passenger train has to
travel to catch the freight train
Start a stopwatch when the passenger train leaves
Let t = the time on the stopwatch when they meet
Equation for freight train:
d-240=60t
Equation for passenger train:
d=100t
all together:
100t-240=60t
we can do 100t-60t because they both have (t)= 40t
40t=240 *now divide 240 by 40= 6
THEN do:
D= 100mph x 6= 600mi
They will meet 600 mi from the station
to check:
d-240=60t x 6
600-240= 360
60 x 6= 360
360=360

Answer:
4% Hope this helped.
Step-by-step explanation:
The formula is: final value minus starting value divided by the starting value then times 100
THIS FORMULA ONLY APPLIES TO PERCENT INCREASE
<u>Final Value−Starting Value</u>
Starting Value x100
Plug numbers in
2600-2500/2500 x 100
100/2500=0.04
0.04x100
=4%
The variable X (percentage) over 100 and 23 over 80.
