Litzy Mclaughlin · Answer 1

Time = (distance) / (speed)

Distance = 8 cm or 0.08 meter

Time = (0.08 meter) / (3 meter/sec)

Time = (0.08 meter) · (sec / 3 meter)

Time = (0.08 / 3) (meter-sec/meter)

Time = 0.027 second

Jolie Kline · Answer 2

8cm is 0.08metres

if 3 metres per second,

time = distance/speed

time = 0.08/3

0.027 second
