Peter can cover a certain distance in 1 hr. 24 min. by covering two-third of the distance at 4 kmph and the
rest at 5 kmph. Find the total distance. Select the correct option:	A) 4 km	B) 5 km	C) 6 km	D) 7 km	E) 8 km
time=distance/speed   let total distance travelled be x in 84/60 hrs   2/3 rd of x travelled in 4 km/hr   1/3 rd of distance travelled in 5 km/hr   2x/(3*4)+x/(3*5)=84/60   x=6 km   ANSWER:6 km
