(1) 33 kms
(2) 132 kms
(3) 36 kms
(4) 144 kms

-
- If D is the distance, then
D/ 3.67 - D/4 =3
0.33 *D = 3*4*3.67
D= 12*3.67/0.33 = 133.45 kms = approx. 132 km .. option 2 - 13 years agoHelpfull: Yes(2) No(0)
- x be the distance now given
4 = x/t , also
3.67 = x/(t+3)
t=367/11 hour
so x= 4*367/11 = 133.45 i.e. 132 approx - 7 years agoHelpfull: Yes(1) No(0)
