A) 144m
B) 240m
C) 120m
D) 96m
E) 320m
Correct Answer: B
Solution :
\[\because \]\[\frac{2}{3}\times 48={{e}^{2}}=48\] \[\Rightarrow \] \[e=\sqrt{\frac{2}{3}}\] \[\therefore \]Total travelled distance \[=\frac{1+\frac{2}{3}}{1-\frac{2}{3}}\times 48\] \[=\frac{\frac{5}{3}}{\frac{1}{3}}\times 48=5\times 48\] \[=240\text{ }m\]You need to login to perform this action.
