Answer:
Step-by-step explanation:
Given the speed of Stephano’s marble is represented by the equation
f = 2.25s, where f is the distance in feet and s is the time in seconds.
To get the marble that will reach the 6-foot mark sooner, we will substitute the value of f = 6 and calculate the value of s as shown:
f = 2.25s
6 = 2.25s
s = 6/2.25
s = 2.67secs
Hence the 6 foot marble will reach after 2.67secs
