Jack and Paul are running 1000m. Jack runs 1.5Km/hr faster than Paul but also finishes the race 1.5 sec earlier. What is the speed of Jack??	Choose the correct option:	A) 20.61	B) 21.61	C) 22.61	D) 23.61	E) 24.61
distance(given) 1000m   paul speed(let)= x m/s   time(paul take)= 1000/x sec   jack speed= x + 1.5*(5/18) m/s   tym (jack)= 1000/(x+7.5/18) s   tym(paul) - tym (jack) = 1.5   solving for x we get 20.20   speed of jack is 20.20+ 7.5/18=20.61   20.61NSWER:20.61
