Answer:
(a) x
(b) x
(c) 2x
(d) 260-2x
Step-by-step explanation:
The initial and final location of Aaron and Emma has been shown in the figure (a) and (b) respectively.
Let v ft/s be the walking speed of Aaron towards Emma.
As both are moving towards each other at the same speed, so, the walking speed of Emma will be v ft/s towards Aaron.
Let after time, s, Aaron covered the distance x feet.
As distance= (speed) x (time)
So,
(a) The expression for the number of feets Aaron walked towards Emma after time t s is x. [given]
(b) Number of feets Emma walked towards Aaron in the same time
From equation (i),
So, the expression for the number of feets Emma walked towards Aaron is x
(c) The expression for the total number of feet Aaron and Emma have walked toward one another since they started walking is the sum of distance covered by both.
=x+x
=2x
(d) As shown in figure (a), the initial distance between them=260 feet.
Distance covered by them=2x.
The remaining distance between Aaron and Emma is 260-2x feet.
So, the expression that represents the distance between Aaron and Emma is 260-2x feet.
