Question 280318
Salazar only ran 50 miles in one week. 
While Rodgers ran twice as many miles as Salazar.(100 miles)
----------------- 
Frank ran three times as many miles as Salazar and Rodgers put together.(450 mi 
------------------
If mike were to run 10% of the miles Salazar and Frank ran combined, then mike would run  ? miles.
-------
Equation:
M = 0.10(50+450)= 0.10(500) = 50 miles
