+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.
