Answer:
m = 0.956
Step-by-step explanation:
Yes, you are doing it correctly.
![\begin{array}{rcll}\log(0.00786391)&= & m \times\log(0.0063)&\\\\m & = & \dfrac{\log(0.00786391)}{ \log(0.0063)} & \text{Divided each side by log(0.0063)}\\\\& = & \dfrac{-2.104361}{-2.20} & \text{Took the logarithms}\\\\& = & \mathbf{0.956} &\text{Did the division}\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcll%7D%5Clog%280.00786391%29%26%3D%20%26%20m%20%5Ctimes%5Clog%280.0063%29%26%5C%5C%5C%5Cm%20%26%20%3D%20%26%20%5Cdfrac%7B%5Clog%280.00786391%29%7D%7B%20%5Clog%280.0063%29%7D%20%26%20%5Ctext%7BDivided%20each%20side%20by%20log%280.0063%29%7D%5C%5C%5C%5C%26%20%3D%20%26%20%5Cdfrac%7B-2.104361%7D%7B-2.20%7D%20%26%20%5Ctext%7BTook%20the%20logarithms%7D%5C%5C%5C%5C%26%20%3D%20%26%20%5Cmathbf%7B0.956%7D%20%26%5Ctext%7BDid%20the%20division%7D%5C%5C%5Cend%7Barray%7D)
Distance:time=25:13.7
ratio and propriton
4min=60sec*4=240sec
25/13.7=?/240
times both sides by 240*13.7
25*240=13.7?
6000=13.7?
divide both sides by 13.7
437.9562=?
about 438 meters
