Answer:
Ben and Susan will be 340 miles apart
Step by Step Solution
Step 1: We plot the problem on a graph to visualize the problem
Step 2: We notice that the problem creates a right triangle with the distance Ben and Susan travel as the legs of the right triangle
Step 3: We can use the Pythagorean Theorem: a²+b²=c² to solve the distance between Ben and Susan
Step 4: We enter the numbers into the formula
a² + b² = c²
300² + 160² = c²
90000 + 25600 = c²
115600 = c² *square root both sides
c = 340
Therefore Ben and Susan are 340 miles apart
