Explanation:

Step 1: Define

Identify

[Given] v = 30 m/s

[Given] t = 4 s

Step 2: Solve

1. Multiply [Cancel out units]:                                                                            30 m/s · 4 s = 120 m

Answer 2

Answer:

$\boxed {\boxed {\sf 120 \ meters}}$

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.
