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

Answer 1

Answer

Distance between Dallas to Atlanta = (150 x - 100) miles

For, a Round trip we have to calculate total Distance which is

 =Distance between Dallas to Atlanta +Distance Between Atlanta to Dallas

 =2 × Distance between Dallas to Atlanta

 = 2 × (150 x - 100)

 = 2 × 150 x - 2 × 100→→Using Distributive property of Multiplication with respect to Subtraction

= (300 x - 200) miles,

Which is a single expression that represents the distance for a round trip flight.

Answer 2

One way distance is 150x-100
so for roundtrip it is  2(150x-100)
