Q:

In a race of 800m Kaushik gives Piyush a start of 200m and then loses the race by 20 seconds. What is the speed of Piyush and Kaushik respectively ? If the ratio of respective speeds be 3:2.

Answer

Let the speed of Kaushik be Sk and speed of Piyush be Sp and let the time taken by Piyush be t second then,


 SkSp = 800t+20600t = 23since given ratio


 


t = 20 s


 


Speed of Piyush = Sp = 600/20 = 30 m/s


 


and    Speed of Kaushik = 800/40 = 20 m/s
