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

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

Answer 2

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.
