We can fit the data to a linear model of the form:
y = kx
To find the value of k, we can solve for it from the above equation, like this:
y=kx
y/x=kx/x
y/x=k
k=y/x
By taking the pair (1.5 , 3), we can find k like this:
k= 3/1.5 = 2
Now that we know the value of k, we can use the above formula y=kx and substitute each value of time from the table and then calculate the corresponding distance, like this:
with time equals 0.5 h
y=2*0.5=1
With time equals 1 h
y=2*1=2
With time equals 2 h
y=2*2=4
With time equals 2.5
y=2*2.5=5
With time equals 3
y=2*3=6
Then, the table with the missing values looks like this:
