Let d(t) be the total number of miles Joanna has cycled, and let t represent the number of hours after stopping for a break duri
katrin [286]
For this case we have the following equation:
 d (t) = 12t + 20&#10;
 The variables are:
 t: time in hours
 d (t): distance traveled in miles.
 We evaluate the distance traveled after 4 hours.
 So we have that for t = 4:
 d (4) = 12 (4) +20&#10;&#10;d (4) = 48 + 20&#10;&#10;d (4) = 68
 Answer:
 
d (4) = 68
 
This means that after 4 hours Joanna cycled for 68 miles total
