20 points... Fiona is walking at a constant speed in front of a motion sensor. After 2 s, she is 1.5 m from the
sensor. 2 s later, she is 4.5 m from the sensor.
a) Is Fiona moving toward or away from the sensor? How do you know?
b) How fast is Fiona walking? (find the slope)
c) Find the equation that describes Fiona's motion in the form d = mt + b
d) What is the d-intercept and what does it represent?
How do I solve this?
