I think the answer is +20 because area under the graph depicts velocity. so area of positive slpoe or triangle is +30 and negative is -10...on solving the answer is +20...i still am not sure
pardon me bur.... the area under the curve is equals to the change in velocity... not just velocity ..!
yeah i now know..i know the answer is not +20 its +15 when i solved it again i got the answer
oohyy
oh! okay
