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:
Step-by-step explanation:
Answer:
65.63%
Step-by-step explanation:
21: 32*100 =
(21*100): 32 =
2100: 32 = 65.63
Lets say 'x' is the number.
so you do 6/100 times x= 20/100 times 6
and that equals 6/100x=6/5
x=20
good luck!
