Question

does anyone have time to help me with a word problem?

Answer 1

shoot

Answer 2

lol, same problem. #13. like i don;t know how to calculate it.

Answer 3

Ah yes I missed your reply. Using the formula you gave me, input the numbers from the graph.

Answer 4

e.g. how far did he move and how long did it take?

Answer 5

1.5 / 1?

Answer 6

He moves 2m in 4 seconds, do you agree? If so, what is then the speed?

Answer 7

.5

Answer 8

but isn't it first 1.5 divided by 1?

Answer 9

then 2 / 2

Answer 10

then; 2.5 / 3

Answer 11

and 3/ 4

Answer 12

No. Remember we said that if the slope stays the same then that means the speed stays the same? 0.5 is correct.

Answer 13

Ohh, then why is it 2 /4 ?

Answer 14

The y axis is position, so he starts out at 1m and move to 3m, so he has travelled a total of 2m. On the x axis he started at time = 0 and finished at time = 4 so he took 4s.

Hence he took 4s to travel 2m, meaning his speed is 0.5metres per second

Answer 15

wouldn't it be 3?

Answer 16

since thats where it stopped.

Answer 17

but he started at 1, so if he stopped at 3, he only moved 2metres

Answer 18

ohhh i see it! :)

Answer 19
