Answer 1

The car is travelling above the speed limit.

Explanation:

Speed of car = 70 km/h

Speed limit = 40 miles per hour

There are 0.62 miles in 1 kilometer.

1 kilometer = 0.62 miles

70 kilometer = 0.62 * 70 miles

70 kilometers = 43.40 miles

As,

43.40 > 40

Therefore,

The car is travelling above the speed limit.
