Answer:
9. 34 10. 8
Step-by-step explanation:
Let
x = time of Byran's work
x + 10 = time of Andy's work
Rate is usually expressed a reciprocal. The total rate will be 12 minutes.
1/x + 1/(x + 10) = 1/12
The value of x will be 20 minutes.
Therefore Byran can take 20 minutes while Andy can take 30 minutes.
