Lindsay is late to class and is running down the hallway at a speed of 2 m/s the length of the hallway is 150 meters . How long will it take her to run down the hallway?

75seconds

Explanation:

Speed is the distance covered in metres per unit time.

Hence Speed = Distance / Time taken

Since Distance covered = 150 metres

Speed of Lindsay = 2m/s

Make Time taken the subject formula

Thus, Time taken = (Distance /speed)

Time taken = (150m / 2 m/s)

= 75 seconds

Thus, it will take Linsday 75 seconds to run down the hallway.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
