Answer:
3 hours
Step-by-step explanation:
Albert already finished 6 oil changes
He works at a rate of 1 oil change per hour
Let x be the number of hour at which they will be tied ie equal
For Albert, we have the sum of a constant and his hourly work rate: 6+1x
Brad works at a rate 3 oil changes every hour: 3x
6+1x=3x
3x-1x=6
2x=6
x=6/2=3
After 3 hours, they will be tied.
