Employs delivery people (4 are new hires)
Customer complaints about excessively long delivery times.

SnowPea wants to advertise that it can achieve a total delivery time of no more than 25 min within a 10-mile radius.
If orders take longer than 25minutes, they will give a $10 gift certificate on the customers next purchase.

+Conclusion
SnowPea is unable to achieve their desired time of delivering in more than half the time—both in travel time alone and prep & travel time together.
There is a 15% chance that they do not meet the requirements; resulting in giving out $150 in gift certificates. (TRAVEL TIME ONLY)
There is a 39% chance that they do not meet the requirements; resulting in giving out $390 in gift certificates. (PREP & TRAVEL TIME)
Drivers 1 & 2 take the longest time in delivering orders and should consider speeding up the pace in making deliveries.
