Answer 1

choices (please post these next time)

A)
between 5 and 6 hours
B)
between 6 and 7 hours
C)
between 7 and 8 hours
D)
between 8 and 9 hours

Answer 2

surefire method: distance = rate*time
plug in your distance (475 miles), rate (62 miles/hr) and solve for time

intuitive method: you can round 475 miles up to 480 and 62 miles down to 60, then the calculation becomes 480 miles/60 mph. since you rounded distance up and time down, the actual answer should be a little less than your calculation, which will tell you which time range it should fall into
