Answer:

220 km  

Step-by-step explanation:

Since the direction north is perpendicular to the direction east, the driver has covered the two legs of a right triangle.  The hypotenuse is his displacement for the combination of the two segments.

    D = √(215² + 45²)

        =  √(46,225 + 2,025)

        =  √48,250  =  219.6588... km

Nearest whole number:   220 km
