Question

A lift can travel from Level 1 to Level 5 in 20 seconds. The height between one level and the next is 10 m. Find the speed of the lift in m/s.​

Answer 1

To find the speed of the lift in m/s, we can use the formula:

Speed = Distance / Time

In this case, the distance traveled by the lift is the height between Level 1 and Level 5, which is 10 meters per level, and the time taken is 20 seconds.

Let's calculate the speed:

Distance = 10 meters/level * 4 levels (from Level 1 to Level 5) = 40 meters

Time = 20 seconds

Speed = 40 meters / 20 seconds = 2 meters per second (m/s)

So, the speed of the lift is 2 meters per second.
