Gymsum are you doing this on purpose?
Here you will get a (simple)calculation lesson.
I've tried to do it like you described. But then with right anwsers.
distance between gymsum and raptor
20 meters
acceleration raptor: 4m/s2
topspeed raptor:10ms
speed gymsum 6m/s.
Here you go with your 2,5 sec acceleration.
2,5 * 10 / 2= 12,5m
Here you see the human is faster
2,5 * 6 = 15m
Wow 2,5 meters more distance.
15-12,5 = 2,5m
Now it is 22,5meter.
20+2,5=22,5m
Speed difference is 4m/s, how much seconds.
22,5/4 = 5,615s
And here we see the distance the human has walked before it was eaten.
(5,615+2,5) *6=
8,125*6 = 48,75
And just as you, it is all calculated with that gray stuff, up there in my head that the whole time screams, just use a calculator .
As for the second question, you may anwser it simple. You may also try it with that the raptors changes every second it angle or something.
Imagine that the raptor exactly knows what you're going to do, as some kind of mindreader. Inmidiatly he takes the right angle to get you and he goes in a straight line. This means that the angle where you survive the longest, is the point where both raptors get you at desame time. Remember they go in a straigt line inmidiatly to the point where they are going the eat you.
Use a calculator, and think well. Just act like this is a test. Maybe then we'll think you're smart
