Answer :
The formula that describes this function is c = 50t + 200
What is a Linear equation
A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the y intercept.
Let c represent the distance june has traveled after time t.
Since the cities are 200 miles apart, hence b = 200. Also the spoeed is 50 mph, hence m = 50:
c = 50t + 200
The formula that describes this function is c = 50t + 200
