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
