In order to compute the time it'll take for the train to go from Barcelona to Paris we need to divide the distance of the route he'll take by the average speed at which he'll perform the route. So we have:

time =distance/ (average speed)

time = 650/130 = 5 h

He'll take exactly 5 hours to make this trip.

14. The diagonals of square ABCD intersect at E. If AE = 2, find the perimeter of ABCD.

lutik1710 [3]

Answer:

B, $8\sqrt{2}$

Step-by-step explanation:

Diagonals of a square are congruent so AC= 4

using pythagorean theorem we can then do $x^{2} +x^{2}$ = $4^{2}$

$2x^{2} = 16\\x^{2} =8\\x=\sqrt{8} \\x=2\sqrt{2}$

Then for perimeter we times the $2\sqrt{2}$ by 4 and get

$8\sqrt{2}$

Hope this helps and please mark brainliest!!
