A) 15.6
B) 16.8
C) 17.2
D) 18
Correct Answer: B
Solution :
Total length (distance)\[~=\left( \text{11}0+\text{17}0 \right)\text{m}=\text{28}0\,m\] Speed \[=\text{6}0\,km/h=\text{6}0\text{ }\times \frac{5}{18}=\frac{50}{3}\,m/s\] Hence, required time \[=\frac{Length(\text{distance})}{Speed}\]\[=\frac{280\times 3}{50}=16.8\,s\]You need to login to perform this action.
