Quick im giving 21 points and a brainliest award peter had a 12: 00 noon appointment that was 60 miles from his home. he drove from his home at an average rate of 40 miles per hour and arrived 15 mins late. at what time did peter leave home

V...speed = 40 mph
s...distance = 60
t...time

if he was 15 min late he arrived at 12:15

v=s/t => t=s/v
t = 60/40 = 1.5 h = 1h and 30 min

if he arrived at 12:15 and he was driving for an hour and a half just substract
12:15 - 1:30 = 11:15 - 0:30 = 10:45

he left at 10 45
