The distance from Santa Maria to Los Alamos is 16.25 mi. what is the distance in meters?
Radda [10]

Answer:

26,167.47m

Explanation:

Problem:

We are to solve this problem using dimensional analysis:

  from the given conversion factors-

      0.621mi = 1.00km

       1km = 1000m

From the problem, we are groing from miles to metres:

      16.25mi x \frac{1km}{0.621mi} x \frac{1000m}{1km}

The mi will cancel out and also the km. This leaves us with the desired unit we want which is meters, m.

       =  26,167.47m
