Answer:
(40-20)/.10
Step-by-step explanation:
40-20 is 20, 20 divided by .10 is 200, she used 200 extra minutes.
Answer:

Step-by-step explanation:

Answer:
12
Step-by-step explanation:
Because y=24 and x=2 you do the following:
144/24=6
Then, 6x2=12 because it is proportional
Or you could do 24/2=12 and 144/12=12
v₀ = initial velocity of the freight train while it approach a road crossing = 16 km/h = 16 (5/18) m/s = 4.44 m/s
v = final velocity of the freight train after it crosses a road crossing = 65 km/h = 65 x 5/18 m/s = 18.06 m/s
t = time to do so = 10 min = 10 x 60 sec = 600 sec
acceleration is given as
a = (v - v₀ )/t
a = (18.06 - 4.44)/(600)
a = 0.023 m/s²
a = 294
