At the end of the $7$ seconds, how much will the odometer reading increase by (in m)? $0$ $3$ $4$ $5$ Quantitative Aptitude gate2016-ec-3 quantitative-aptitude speed-time-distance data-interpretation + – makhdoom ghaya asked Jan 25, 2017 edited Jun 20, 2019 by ajaysoni1924 makhdoom ghaya 4.8k views answer comment Share Follow See all 0 reply Please log in or register to add a comment.
Best answer 6 votes 6 votes Odometer is a device used to measure distance traveled by an object. Area under Velocity-Time graph represents the distance traveled. So, answer $= 0.5+1+1.5+1+0.5+0.5= 5 m.$ Correct Answer: $D$ akashsheoran answered Jan 25, 2017 edited Apr 28, 2019 by Naveen Kumar 3 akashsheoran comment Share Follow See all 5 Comments See all 5 5 Comments reply Show 2 previous comments yg92 commented Feb 9, 2017 reply Follow Share @Arjun Sir. Could you pls help. I am getting confused here - Distance travelled by the object is - Dist travelled by moving fwd ( 0 - 4 sec) + Dist travelled in reverse direction ( 5 - 7 sec ) Total dist travelled = 4 m ( moving fwd) + 1 m ( reverse direction) = 5m They have asked - how much will the odometer reading increase? You said distance travelled in reverse direction which is not detected by any odometer. So should the ans include reverse dist covered or exclude that? 0 votes 0 votes Arjun commented Feb 9, 2017 reply Follow Share I meant that odometer won't detect the "reverse" direction and subtract that distance. 0 votes 0 votes itsvkp1 commented Aug 25, 2017 reply Follow Share negative velocity means object is going in reverse direction . odometer is use to measure the distance covered so odometer will still measure the distance cover by object , no matter what is the direction of object. 2 votes 2 votes Please log in or register to add a comment.
