# M1 speed time graph question watch

1. hi can someone explain how to draw the graph for part a . The answer is a b shape graph but I have got a different answer. I think that's to do with the difference between a velocity time graph and a speed time graph . Attachment 544353544355 I don't get why my answer is wrong. Thanks.

Is this because speed is always positive and the graph I drew is a velocity time graph ?
