A) \[\frac{1}{4}\]
B) \[\frac{1}{2}\]
C) \[\frac{1}{8}\]
D) \[\frac{1}{6}\]
Correct Answer: B
Solution :
Travelling distance in last 2 second = Area of C \[=\frac{1}{2}\times 2\times 10=10\,m\] Total distance in 7 s = Area of A + Area of B + Area of C \[=\frac{1}{2}\times 2\times 10+2\times 10+\frac{1}{2}\times 2\times 10\] \[=40m\] The ratio of distances\[=\frac{10}{40}=\frac{1}{4}\]You need to login to perform this action.
