Question 1010721: Sarah wants to find out how much time it would take to drive from her home to New York. At an average, she would drive at 55 miles per hour. If the distance to be covered is 1150 km and a mile equals 1.61 km, how much time will the trip take (to the nearest hour)?

1150 km / 1.61 km / mile = 714.2857 miles.

714.2857 miles / 55 miles / hour = 12.987 hours = 13 hours.

rate * time = distance
time = distance / rate
rate = distance / time
kilometers / 1.61 = miles
miles * 1.61 = kilometers

using miles = kilometers / 1.61, you get:
1150 kilometers / 1.61 = 714.2857... miles

using time = distance / rate, you get:
714.2857 miles / 55 miles per hour = 12.9870... hours.

round that to the nearest hours gets you 13 hours.
