Awoman walks a constant speed of 4.5km per hour. how long will it take her to walk 10 km? use the formula d=st. write the answer in hours and mintues rounded to the nearest minute.

d =st

distance = speed * time

10 = 4.5 * t

divide each side by 4.5

10/4.5 = t

100/45 = t  (can't have a decimal in a fraction so I multiply by 10/10)

divide top and bottom by 5

20/9

2 and 2/9 hours

 to get minutes multiply 2/9 by 60

2/9 * 60

120/9

13 3/9

13 1/3 minutes

2 hours 13 1/3 minutes

to the nearest minutes

2 hours 13 minutes
