J is faster than P. J and P each walk 24 km. Sum ofthe speeds of J and P is 7 kmph. Sum of time taken by them is 14 hours. Then J speed is equal to?
Pick
A) 4  B) 5  C) 6  D) 7  E) 8
let j's speed is x then p's speed would be 7-x.   and given,   sum of time taken by them is 14 hours   =&gt;(24/x)+(24/(7-x)=14   =&gt;x=4,3   therefore j's speed will be 4 as j walks faster than p.   4NSWER:4
