Answer:
2.5 hours
Step-by-step explanation:
The price of stock A is described by ...
A = 14.63 + 0.09t . . . . . . where t is time in hours after 9 A.M.
And the price of stock B is ...
B = 15.13 - 0.11t
The two prices will be equal when ...
A = B
14.63 +0.09t = 15.13 -0.11t
0.20t = 0.50 . . . . . . . . . . . . . add 0.11t -14.63 to both sides
t = 0.50/0.20 = 2.5
The prices of the two stocks will be the same in about 2.5 hours.
