Mary drove for four hours on an interstate highway at a constant rate of 60 miles per hour. During the next hour, she drove on a state road at a slower rate of 40 miles per hour. How many miles did Mary travel on her trip?

280

Step-by-step explanation:

60 x 4 = 240 miles

40 x 1 = 40 miles

240 + 40 = 280 miles

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
