a freight train must approach a road crossing at 16 km/h. After passing through the intersection, the train speeds up rto 65km/h

grin007 [14]

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

The question is:

Naddik [55]

Answer:

2.5 gallons of the 20% solution must be replaced by the 36% solution.

Step-by-step explanation:

$.12(20 - x) + .36x = 20(.15)$

$2.4 - .12x + .36x = 3$

$2.4 - .24x = 3$

$- .24x = - .6$

$.24x = .6$

$x = 2.5$
