Answer:

For every extra mile an employee drives, the driving time increases by 1.3 minutes.

Step-by-step explanation:

y = 1.3x + 6.8

x is the number of miles, y is the time taken

each extra mile, the time increases by 1.3  and the constant is 6.8

say that x = 3, the time taken y = 1.3(3) + 6.8

= 3.9 + 6.8

y =10.7

the difference is 1.3.

for each extra mile, the time is increases by 1.3 minutes.
