Question

if a car is travelling at a speed of 50.0meter/second, is the driver exceeding the speed limit of 100.0mi/h?

Answer 1

1 metre per second =3.6 kilometres per hour

1mi/hour = 1.60934 km/hr

100 miles per hour = $100 × 1.60934 = 160.934 km/hr$

$=3.6×50=180km/hr$

180km/hr is more than 100mi/hr( 160km/hr), hence the driver is exceeding.
