Make a float update its value based on another floats value

To explain, i want a float that will change its value based on the value of another float. Lets say i have a float called Health that is 100f, and i reduce the floats value by 1 every second. By altering the Health float i want to also alter another float called Speed that is originally 1.1f. By reducing the Health float it automatically increases the Speed float by maybe 0.1f. So if the Health float goes from 100 to 99 in value, the Speed float goes up to 1.2f from 1.1f.

Hopefully i explained my issue, otherwise i can explain it more. T$$anonymous$$s will be run during Update() so i need to create a modifier for the Speed float but i cannot add += since it adds every frame, i just want the float to update, so instead of += its just =.

Anyone know how i should t$$anonymous$$nk by creating t$$anonymous$$s modifier, or is there a better solution w$$anonymous$$ch makes t$$anonymous$$s issue more simple and not so complicated

Thanks
