Problema Solution

Two cars one traveling 10 miles faster than the other car start at the same time from the same point and traveled in opposite direction in three hours they are 300 miles apart find the rate or each car

Answer provided by our tutors

fast car lets call d1=(r+10)3 or 3t+30

slow car call 300-d1= r3 



substitute value of d1 from 1st equation into 2nd equation 

300-(3t+30)=3t---->270=6t r=45 

slow car = 45 mph

fast car = 55 mph
