Question

Check? :)
Dayton is due north of Richmond, and Easton is 16 mi due east of Richmond. Dayton is 32 mi from Easton.

How far apart are Dayton and Richmond? Round to the nearest tenth of a mile.

Answer 1

Answer 2

Apply the Pythagorus Theorem.

Answer 3

Let the desired distance by x

Then

x^2 + (16)^2 = (32)^2

Answer 4

16 x 16 = 256
32 x 32 = 1,024
1,024 - 256 = 768

Answer 5

square root of 768 = 27.71

so tenth of a mile will be 27.7
the answer is 27.7

Answer 7
