Basically the question is saying that at the pedestrian is at the point where the car and the motorcycle meet

#

But be careful cause the point they meet at isn't the intersection of the 2 graphs

#

It's where the distance they both covered is equal

#

how would you find this point

#

like how I find out when both of their displacements are the samae

#

would I set up 2 equations?!

#

in terms of t seconds?

#

Yea

#

Get the area that each of them covers while accelerating

#

That's the area under the triangle

#

Now you're left with squares

#

So now create an equation in terms of t for for the area under each of the graphs M and C

#

Equate them together to find the t

#

for the car it's going to be (Area under triangle) + 30(t–20)

#

You could also just model the area under the graph for each of them as a trapezium
