A level biology help

I know it's easy but I seem to not be getting it right. The answer is 32 but 0.53 is allowed. I did change in Y/ change in X. Which by my calculation is basically 18/30 which is 0.6

yep the scale is 2 per square so it's 32 (per minute) or 0.53 (per second)

there are 10 squares between 0 and 20, which means a squares represents 2. and it is 2 squares from the top, which is 20-4=16
