Answer :
To calculate the speed of a cart using the formula [tex]v = \frac{d}{t}[/tex], where:
- [tex]v[/tex] is the speed,
- [tex]d[/tex] is the distance,
- [tex]t[/tex] is the time,
we need to plug in the values provided:
- The cart moved a distance ([tex]d[/tex]) of 120 meters.
- It took a time ([tex]t[/tex]) of 40 seconds.
Now, use the speed formula:
[tex]v = \frac{d}{t} = \frac{120 \text{ meters}}{40 \text{ seconds}} = 3 \text{ meters per second}[/tex]
Thus, the speed of the cart is 3 meters per second.
In the multiple-choice options given, the correct answer is 3 meters per second.
