Answer:

4 seconds

Step-by-step explanation:

Assuming that the marble is at a constant speed, then

s = d/t

where:

s = 48 cm/s

d = 1.92 meters

Q: How long did the marble take to roll from one end to other end.

Solution:

1st convert the given centimeters into meters

48 cm/s * 1m / 100cm = 0.48 m/s

to find the "t" from the given formula above.

t = d/s

or

t = 1.92 m / 0.48 m/s

t = 4 seconds.

/.: The marble reached the other end from the other end in just 4 seconds
