    400/50=8m/sec.

    Okay Rubie why don't we start by calculating the speed of your partner. Now you will have to calculate it in sec/m unless that was a typo earlier. I will let you do the calculation and step in if necessary.

    vipul if you are wondering why I said to give it in sec/m it is because that is the way they gave the realtionship between the runners. I may not reply for a few minutes here I need to do something quickly.

    no track your units. the numbers you gave me up there would render m/s the relationship they gave us was in s/m . you need to get those units

    50/400 is the correct first step giving you a speed of 0.125 s/m

    Unfortunately I think you have a typo here as if you are faster than your partner by 4 s/m then your speed is 0.125-4 = -3.75 s/m which is impossible

    \[\frac{ s }{ m }\] or \[\frac{ m }{ s }\] which is the unit your relationship is given in?
