Distance
= Speed × Time
= (8.3 m/s) × (0.6 s)
= 4.98 m
= Speed × Time
= (8.3 m/s) × (0.6 s)
= 4.98 m

IF you ever forget the formula, simply look at the units
8.3m/s has meters on top, that's good. Seconds are on the bottom, so you need to multiply by seconds on the top to cancel out seconds.
8.3 m/s * 0.6 s = 4.98 m

8.3 m/s * 0.6 s = 4.98 m
參考: Many times you can simply use the units to work the problem!!!

speed(s) = distance(m) / time(s)
s = m/s
algebraically rearrange
m = ss'
m = 8.3 m/s x 0.6s
m = 4.98 m (metres)
NB the units 's(seconds)' cancel down .

Less than 8.3m, or .83 x 6
