The fastest speed ever measured for a tennis ball served by a player was 263 km/h.
At this speed, how long does the tennis ball take to go from one end of the court to the other, a distance of 23.8 m?
Distance $s = 23.8$ m
Speed $v = 263$ km/h
Time $t = \frac{s}{t}$
Distance = 23.8 # in m
Speed = 263 /3.6 # in m/s
Time = Distance / Speed
