WEEK 3 and 4 DUE 5/2


Due 5/2

Train A leaves the station heading west at 50mph.  3 hours later Train B starts heading west at 80mph.  They are both going to a destination that is 300 miles away.  Will Train B ever catch Train A?  If so, when?  If not, where will Train B be when Train A reaches the destination?

  1. again klike week 2 i have made a table:

    train a: 50 100 150 200 250 300 350
    train b: 0 0 0 80 160 240 320
    and train b will not catch up to train a it will be behind by 60 miles when train a reaches its destination.

    1. I agree also u have to make a chart to compare them both Train b will be left behind 60 miles & Train B will not catch up with train a - mph , 1,2,3,4,5,6,7 train A. 50.100,150,200,250,300,350 Train B. 0,0,0,80,160,240,320

  2. Train B will never catch up. If you make a chart you will notice that that when Train A reaches it destination, Train B will be 60 miles behind.

    1. I agree with nikola because if you make a chart. It will show that when train A reaches its destination train B will be 60 miles behind.This proves that train B will reach its destnation last

  3. You should make a chart. And you will figure out that train a will go faster. It will go 60 miles faster.

  4. Train B will never catch up with Train A. I can prove it by making a graph.

    Train A
    miles 50 100 150 200 300 350
    hours 1 2 3 4 5 6

    Train B
    miles 0 0 0 80 160 240 320
    hours 1 2 3 4 5 6 7 Train B will never catch up because train b will be 60 .........................................miles behind of train A.

  5. I agree with everyone who says that Train B will never catch up with Train A.
    As they have said, Train B will only have gone 240 miles when Train A reaches it's destination, difference of 60 miles.
    This week, we worked on OAA practice packets to get ourselves ready for the upcoming Math OAA.

  6. Yes, I agree that train A will always be ahead and train be will never catch up. It will take only 6 hours for train A to reach its final point and by that time, train B will still only be at 240 miles. There is a 60 mile difference between the two. (300-240=60)
