(A) Speed of the tractor $= \frac{360\,km}{12\,h} = 30\,km/h$.Given the ratio of speeds of car,jeep,and tractor is $3:5:2$. Let the speeds be $3x$,$5x$,and $2x$ respectively.Since the speed of the tractor is $30\,km/h$,we have $2x = 30$,which implies $x = 15$.Speed of the car $= 3x = 3 \times 15 = 45\,km/h$.Speed of the jeep $= 5x = 5 \times 15 = 75\,km/h$.Average speed of the car and the jeep $= \frac{45 + 75}{2} = \frac{120}{2} = 60\,km/h$.
