Question

A one-way flight from Dallas to Atlanta is "150x − 100" miles. Find a single expression that represents the distance for a round trip flight.

A) 300x
B) 300x + 200
C) 300x − 200
D) 300x − 400

Answer 1

Answer: 300x-200

Step-by-step explanation: if we have a round trip, then you have to multiply by 2.

(150x-100)*2

Answer 2

The one-way flight is represented as 150x-100miles. If we have a round trip distance to be computed, then we need to multiply it twice such as the solution is shown below:
(150x-100)*2
300x-200
Therefore, the answer is letter "C" which is 300x-200.
