A) 177 m
B) 103 m
C) 83 m
D) 73 m
Correct Answer: D
Solution :
Let P be the starting point of his run, then PT is the distance between the starting and the finishing point. |
\[\therefore \] \[PU=RQ-ST=60-12=48\,\,\text{m}\] |
\[TU=RS-QP=80-25=55\,\,\text{m}\] |
\[\therefore \]In \[\Delta PUT,\]\[P{{T}^{2}}={{(PU)}^{2}}+{{(TU)}^{2}}\] |
\[\therefore \] \[PT=\sqrt{{{(48)}^{2}}+{{(55)}^{2}}}=\sqrt{5329}=73\,\,\text{m}\] |
