Answer:
15 minutes
Step-by-step explanation:
Betty mows at 3 times the speed that Bullwinkle does, so is equivalent to having 3 Bullwinkles in her place. That makes the lawn get mowed as though 4 Bullwinkles were working, so it will take 1/4 the time it takes Bullwinkle to mow the whole yard. 1/4 of 60 minutes is 15 minutes.
Working together, Betty and Bullwinkle will take 15 minutes to mow the lawn.

Answer:
80 feet
Step-by-step explanation:
According to the tangent-secant theorem, the square of the tangent length is equal to the product of the secant segment and the external portion.
In other words:
30² = (10 + x) (10)
900 = 100 + 10x
800 = 10x
x = 80
