The formula for finding time is the distance divided by the velocity.So the answer is 100÷30=3.3333...
m=18 when r = 2.
Step-by-step explanation:
Given,
m∝
So,
m = k×
,--------eq 1, here k is the constant.
To find the value of m when r = 2
At first we need to find the value of k
Solution
Now,
Putting the values of m=9 and r = 4 in eq 1 we get,
9 = 
or, k = 36
So, eq 1 can be written as m= 
Now, we put r =2
m = 
or, m= 18
Hence,
m=18 when r = 2.
