Question

An object rolls east at a steady speed of 12 m/s for 3.0 seconds. What distance did it travel?

O A. 36 m
o B. 24 m
O C. 18 m
O D. 7.0 m

Answer 1

`\boxed {\boxed {\sf A. \ 36 \ m}}`

Step-by-step explanation:

The distance an object travels is the product of its speed and time.

`d=s * t`

The object's speed is 12 meters per second and the time is 3 seconds.

• s= 12 m/s
• t= 3 s

Substitute the values into the formula.

`d= 12 \ m/s * 3 \ s`

Multiply. Note that the units of seconds will cancel, so we are left with meters as our units.

`d= 12 \ m * 3`

`d= 36 \ m`

The object travels a distance of 36 meters and choice A is correct.
