A man covered a certain distance at some speed. Had he moved 3 kmph faster, he would have taken 40 minutes less. If he had moved 2 kmph slower, he would have taken 40 minutes more. The distance (in km) is:	Pick:	A) 35	B) 36	C) 37	D) 40	E) 45
According to given condition   vt=(v+3)(t-2/3)   vt=(v-2)(t+2/3)   here v is velocity in kmph, t is time in hours and 2/3 is value of 40 min in hour   on solving we will get t=10/3 and and v = 12 so distance = (10/3) * 12=
