What should a person in a wheelchair or crutches use to avoid injury when going up or down a level in a building?

Car
Door
Ramp
Stairs

Well if they are in a wheelchair they should probably use a ramp.

Hope I Helped!!

most likely a ramp because the person using a wheelchair would not be able to use stairs, and that is the only other one to get up or down levels

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
