Answer:
4.45 m/s
Step-by-step explanation:
Vertical distance, Sy = 5m
The speed of pebble when they hit her window :
Vx = Sx / t
We can obtain t using the relation :
Sy = 1/2 * at²
Where, a = acceleration due to gravity = 9.8m/s²
We can obtain t
5 = 1/2 * 9.8 * t²
5 = 4.9t²
t = √5/4.9
t = 1.01 seconds
Hence,
Speed, Vx = Sx / t
Vx = 4.5 / 1.01
Vx = 4.45 m/s

There are many different combinations, but this seems to be the most practical
There is no underlined digit that I see, but I think they're asking you to just round. In that case the answer would be 0.4
Moving the decimal point TWO places to the right you get the answer for the conversion of meters to centimeters. SO 3.9 meters in centimeters is 390 meters
