The Attempt at a Solution
I've figured it out using a method I was previously taught, but it seems that according to the official answers, the motorcycle overtakes at 32.5seconds.
Here is what I did anyhow..
Motorcycle displacement = 100t - (850)
[The 850 came from the sum total of the triangle and the trapezium]
Car displacement = 80t - 650
[Similarly the 650 came from the sum total of the triangle and the trapezium]
Equating the two...
100t-850 = 80t-650
20t = 250
t = 12.5 seconds
