The velocity-time graph of a car moving along a straight road is shown in figure. The average velocity of the car in first 25 seconds is A. `20 m//s`B. `14 m//s`C. `10 m//s`D. `17.5 m//s`

Answer» Correct Answer - B
`"Average velocity"=(int_(0)^(25)vdt)/(25-0)=("Area of" v-t "graph between" t=0 "to" t=25s)/(25)[((25+10)/(2))(20)]=14 m//s`
