[d] Length of the train \[=x\] metres \[\therefore \] Speed of the train \[=\frac{x}{1.75}\] m.p.sec. Speed of the train relative to speed of the cyclist \[=\left( \frac{x}{1.75}-10 \right)\]m.p. sec \[\therefore \,\,\,1.5=\frac{x}{\left( \frac{x}{1.75}-10 \right)}\Rightarrow x=105\,\,m\]You need to login to perform this action.
