A) 1190 m
B) 850 m
C) 595 m
D) 510 m
Correct Answer: B
Solution :
\[2{{d}_{1}}+2{{d}_{2}}=v\times {{t}_{1}}+v\times {{t}_{2}}\]Þ \[2({{d}_{1}}+{{d}_{2}})=v({{t}_{1}}+{{t}_{2}})\] \[{{d}_{1}}+{{d}_{2}}=\frac{v({{t}_{1}}+{{t}_{2}})}{2}\]=\[\frac{340\times (1.5+3.5)}{2}=850\] m.You need to login to perform this action.
