Question

6. Jack and Jane are initially separated by a distance of 160 m.
a) If Jack and Jane starts to move towards each other with a speed of 1 m/s at the same time, how long would it take for them to meet at the same position?

Answer 1

80s

Answer 2

May i know how did you get the answer ? thank you.

Answer 3

since they have the same rate/ you can conclude that they will meet at a point wherebthey have equal distances. That makes their distance both 80m. Since they can move 1 mile per second, 80 miles would be 80 seconds. :)

Answer 4

Does that answer your question??

Answer 5

Yes. Thank you very much :)

Answer 6

u can use relative motion.they are coming toward each other so u can sum their rates.1+1=2m/s now u can find the time bye the equation X=VT which tends to 160=2t.solving for t u have T=8O. u can find the distance bye multiplying 80*1=80m

Answer 7

around 42 parsecs. Give or take 2 drizzles, but make sure to convert from swizzles first.
