The elevator rises evenly at a speed of 3m / s. How many minutes the elevator rises to its 90m.

The height to which the elevator rises is the distance traveled and can be calculated using the formula:

S = V * t, where S is the height to which the lift rises (according to the condition S = h = 90 m), V is the speed of the lift rise (according to the condition V = 3 m / s), t is the required lift rise time (s ).

t = S / V.

Let’s do the calculation:

t = 90/3 = 30 s = 0.5 min.

Answer: The elevator will rise 90 meters in half a minute.
