It's kinda more complicated than you might think from the title...

the question asks:

Calculate the distance travelled by the car while it was travelling faster than the truck.

(the graph is attached)

and here is my attempt:

area of left triange= 0.5 * 30 * 24 = 360m

area of right triange= 0.5 * 10 * 24 = 120m

so that area where the speed in highter is 360+120= 480m

but the answer should be 960m.

thanks in advance :-)

btw this forum ROCKS!
