When doing a physics problem, you were asked to calculate how fast a car was going in a particular situation. You came up with an answer of 230 m/s. You want to check if this is plausible, by converting this number into more familiar units: kilometres per hour. What is 230 m/s when converted into kilometres per hour, and is this a plausible speed for a car?
A)230 km/hr: not plausible
B)828 km/hr: not plausible
C)64 km/hr: plausible
D)2.3 km/hr: plausible
E)23 km/hr: plausible

230 m/s is equivalent to 828 km/hr (since 1 m/s = 3.6 km/hr). This speed is not plausible for a car as it is much faster than typical car speeds.
