Answer:
1 minute
Step-by-step explanation:
First, we'll begin by calculating the speed. This is illustrated below:
Data obtained from the question include:
Speed = (1/2)cm / (1/2)min
Half a cm = 1/2 = 0.5cm
Half a minute = 1/2 = 0.5 min
Speed = 0.5cm/0.5min
Speed = 1cm/min
The next target is to obtain the time taken to travel a centimetre(1cm). This can be achieved as shown below:
Speed = 1cm/min
Distance = 1cm
Time =?
Speed = Distance /time
1 = 1/ time
Cross multiply to express in linear form
Time = 1 minute.
Therefore, it will take a minute to travel a centimetre
