Hey there.
Unless I'm mistaken, 1200 metres in 75 seconds means a speed of 1200/75 = 16 metres per second
3/4 of that speed is 16*0.75 , that is 12 metres per second
To run 1100 metres at 12 metres per second, it should take 1100 / 12 that is about 91.6 seconds
Another way to think about it is as follows:
Full pace for 1200 is 75 seconds.
If you change the length of the run to 1100 instead of 1200, that's equivalent to multiplying by 11/12.
And if you run at 3/4 the pace, then indeed it should take 4/3 the time.
75 * (11/12) * (4/3) also equals about 91.6
