Two trains leave towns 474 kilometers apart at the same time and travel toward each other. One train travels13 km/m faster than
guajiro [1.7K]

Answer:

112 km/h

125 km/hr

Step-by-step explanation:

Distance = time * speed

Distance  = distance train 1 + distance train 2

474 = 2(s) + 2(s + 13)

Distribute

474 = 2s + 2s + 26

Combine like terms

474 = 4s + 26

Subtract 26 from both sides

448 = 4s

Divide both sides by 4

112 = s

s = 112 km/h

s + 13 = 125 km/hr

WE has endpoints at<br>W(10, 2) and E(5, -3).<br>How long is WE?​
s2008m [1.1K]

Answer:

WE=5\sqrt{2}

Step-by-step explanation:

Distance between two points:

The distance between (x_1,y_1) and (x_2,y_2) is given by=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2

Hence distance between W(10,2) and E(5,-3)

WE=\sqrt{(5-10)^2+(-3-2)^2}=\sqrt{(-5)^2+(-5)^2}=\sqrt{25+25}\\\\WE=\sqrt{50}=5\sqrt{2}
