------------------------------------------------ Calculate the speed of a cart which moved 120 metres in 40 seconds.

Use the formula [tex]v = \frac{d}{t}[/tex].

A. 3 metres per second
B. 4 metres per second
C. 30 metres per second
D. 40 metres per second

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:

  1. The cart moved a distance ([tex]d[/tex]) of 120 meters.
  2. 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.
