A) 16.7 km
B) 18.6 km
C) 21.5 km
D) 26.7 km
Correct Answer: D
Solution :
Distance covered by A in h \[=4\times 4=16\,km\] Relative speed of B with respect to \[~A=10-4=6\,\text{km/h}\] \[\therefore \] Time taken to catch\[~A=\frac{16}{6}=\frac{8}{3}h\] \[\therefore \] Required distance\[=\frac{8}{3}\times 10=\frac{80}{3}=26.7\,km\]You need to login to perform this action.
