Question 1136630
.
<pre>
Let " d " be the distance under the question.


Then you have this "time" equation


    {{{d/5}}} = {{{(d-15)/4}}}    seconds,


saying that Ahmed and Abdullah spent equal amount of time from the start to the catching (overtaking) moment.


To solve the equation, multiply both sides by 20. You will get


    4d = 5*(d-15)

    4d = 5d - 75

    75 = 5d - 4d

    d = 75.


<U>ANSWER</U>.  75 meters from the starting line.
