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 points. \[\therefore \] \[PU=RQ-ST=60-12=48\,m\] \[TU=RS-QP=80-25=55\,m\] \[\therefore \] In \[\Delta PUT\] \[P{{T}^{2}}={{(PU)}^{2}}+{{(TU)}^{2}}\] \[\therefore \] \[PT=\sqrt{{{(48)}^{2}}+{{(55)}^{2}}}\] \[=\sqrt{5529}=73\,m\]You need to login to perform this action.
