Question

If a car's velocity is 30 m/s and it drives at this velocity for 4 seconds, how far did it go?

Answer 1

`\boxed {\boxed {\sf 120 \ meters}}`

Step-by-step explanation:

Distance, or how far an object travels, is the product of velocity and time.

`d= v*t`

The velocity is 30 meters per second and the time is 4 seconds.

• v= 30 m/s
• t=4 s

Substitute the values into the formula.

`d= 30 \ m/s * 4 \ s`

Multiply. The units of seconds (s) cancel.

`d= 30 \ m * 4`

`d=120 \ m`

The car travels a distance of 120 meters in 4 seconds at a velocity of 30 meters per second.

Answer 2

120 m
