Question

Conner and Alexandra are 260 feet apart when they start walking toward one another. Alexandra walks twice as fast as Conner so whenever Conner travels x feet, Alexandra travels 2 x feet. Let x represent the number of feet Conner has traveled since he started walking toward Alexandra. Write an expression in terms of x to represent the total number of feet Conner and Alexandra have walked toward one another. 3x Correct Write an expression in terms of x to represent the distance (in feet) between Conner and Alexandra.

Answer 1

i) 3x

ii) d = 260 - 3x

Explanation:

Given:

Conner traveled x feet

Alexandra traveled 2x feet

Total distance = 260 ft

i) The expression in terms of x to represent the total number of feet Conner and Alexandra have walked toward one another will be:

This will be the total number of feet they have walked towards one another

= x + 2x

= 3x

ii) An expression in terms of x to represent the distance (in feet) between Conner and Alexandra.

This will be to find the distance between Conner and Alexandra.

Thus, distance between them will be:

d = 260 - (x + 2x)

d = 260 - 3x
