On a snow day, Mason created two snowmen in his backyard. Snowman A was built to a height of 51 inches and Snowman B was built to a height of 29 inches. The next day, the temperature increased and both snowmen began to melt. At sunrise, Snowman A's height decrease by 4 inches per hour and Snowman B's height decreased by 2 inches per hour. Let A(t) represent the height of Snowman A tt hours after sunrise and let B(t)B(t) represent the he ight of Snowman B tt hours after sunrise. Write the equation for each function and determine the interval of time, t, t, when Snowman A is taller than Snowman B.
