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.

x = -15

Step-by-step explanation:

$x = \frac{2}{3} x - 5$

Collect like terms and simplify

$x - \frac{2}{3} x = - 5 \\ \frac{1}{3} x = - 5$

Cross multiply

$x = - 5 \times 3 \\ \\ x = - 15$
