Question
A car is traveling at a speed of 33 m/s33 m/s . (a) What is its speed in kilometers per hour? (b) Is it exceeding the 90 km/h90 km/h speed limit?
Solution
(a) To convert the speed from meters per second (m/s) to kilometers per hour (km/h), you use the conversion factor 3.6 (since 1 m/s is equal to 3.6 km/h).
So, the speed in km/h is 33 m/s * 3.6 = 118.8 km/h.
(b) Yes, the car is exceeding the 90 km/h speed limit because its speed is 118.8 km/h, which is greater than 90 km/h.
