Question

In one second an ant dragged an object 1 mm. What was its speed in cm/min?
​

Answer 1

The speed of the ant is 6
`(cm)/(min)`

Step-by-step explanation:

Speed ​​is a magnitude that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, velocity relates change in position (or displacement) with time by:

`speed=(distance)/(time)`

In this case:

• speed= ?
• distance= 1 mm
• time= 1 second

Replacing:

`speed=(1 mm)/(1 second)`

Being 1 mm equivalent to 0.1 cm and 1 seconds equal to 0.01667 minutes then:

`speed=(1 mm)/(1 second)=(0.1 cm)/(0.01667 min)`

speed = 6
`(cm)/(min)`

The speed of the ant is 6
`(cm)/(min)`
