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?

20 minutes = 1/3 of an hour

1/3 = 0.333

 1/3 x 45mph = 15, so she drove 15 miles at 45mph

18-15 = 3

3 miles/ 20 mph = 0.15 hours

0.333+0.15 = 0.483 hours total

0.483 x 60 = 28.98 so approximately 29 minutes total driving time

7:15 + 29 minutes is 7:44 am she arrived at work

answer is : muchas/tipicas

have a nice day!
