A) 2001 km
B) 180 km
C) 160 km
D) 220 km
E) 210 km
Correct Answer: B
Solution :
Let the total distance be D km According to the question, \[\frac{D}{14+4}+\frac{\frac{D}{2}}{14-4}=19\] Or \[\frac{D}{18}+\frac{D}{20}=19\] or\[\frac{10D+9D}{180}=19\] \[\therefore 19D=19\times 180\] \[\therefore D=180km\]You need to login to perform this action.
