1 answer:
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
