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
260 miles/12 gallons ≈21.7 miles per gallon
286 miles ÷ 21.7 ≈ 13.2 gallons needed
Answer:
Step-by-step explanation:
I'll give a couple answers so you get the gist of things.
All you have to do is substitute 1/2 for x and 3/4 for y.
Ex - 30. x × y = 1/2 × 3/4 = 3/8
num one u divide 8 by hundred multiplied by half to get ur answer
