Question

daisy walked home from her friends house , which is 700m away in 5minutes. she stayed for 30minutes, then walked home for 10 minutes. what is the value of d

Answer 1

The value of "d" on the distance- time graph is 700 meters.

We are given the parameters which can help with our Calculation;

• (5, 700) = Distance of 700 meters walked in 5 minutes
• Then a period of "0" velocity (time in which she stayed in her friend's house).

From the graph:

The first slope(upward slope) on the graph represents Daisy's walk to her friend's house, which is represented by the pair of points (5, d)

Comparing the point on the graph with the point given :

• (5, d) = (5, 700)

d = 700

Hence, the value of "d" on the graph is 700 meters.
