Your customer is located 100 miles from your office.
You can travel an average of 45 miles in one hour. If
you have a 10:30 A. M. appointment and you want to
arrive 15 minutes early, what time do you have to
leave your office?

8:02 AM

Step-by-step explanation:

Find out how many minutes it takes to travel one mile:

60 divided by 45= 1.333334 minutes

It takes 1.333334 minutes to travel 1 mile, how long will it take to travel 100 miles:

1.333 times 100 = 133.3334

133.3334 rounds to 133 minutes

Add 15 minutes because you want to arrive early

133+15=148

Divide it by 60

148 divided by 60 = 2.466667

or do

148-120 (2 hours) = 28 minutes

It will take 2 hours and 28 minutes to get there

10:30-2:28= 8:02

use this formula:

p(a\b) = p(a and b)/p(b).
