The distance from kenya's house to her job is 18 miles. one morning she left her house at 7:15

a.m. she traveled at the rate of 45 miles per hour for 20 minutes, but to traffic she had to slow down to 20 miles per hour. at what time did kenya arrive at work? show your work.

Answer 1

45:60*20=15 miles the distance she traveled at 45 mph
18-15=3 miles she traveled at 20 mph
3/20=0.15 hours she traveled to reach the work
0.15*60=9 minutes
20+9=29 minutes she traveled to work
7:15+29=7:44
Kenya arrive at work at 7:44
