Answer:

27.5

Step-by-step explanation:

first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.

so!

30x30 is 900

12x12 is 144

subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5

  • Use this distance to find the time if speed is 50 miles per hour, so time is derived by dividing the distance by the speed
  • 330 miles divide by 50 miles per hour gives 6.6 hours
