Given is the calculated distance as well as the driving travel time, which does not take into account driving conditions, traffic, etc. The distance between Seattle, Washington and Long Beach, Washington is 171 miles. The resulting travel time is 3 hours and 10 minutes.
171 mi / 120 MPH = 1.425 hr = 1 hr 27 min
Time = Distance/Speed = 171/70 = 2.443 hours (approx)
1/171 of an hour = 3,600/171 = 21.053 seconds (rounded)
171 km = 106.254 miles (rounded)
171/3 = 57 miles per hour
171 kilometers is 106.254 miles

This is the problem: Andrew is driving to visit his grandmother.He drove 171 miles in 3 hours.What was his average rate of travel for the trip?
At 19 miles per gallon times 9 gallons you can travel 171 miles on a full tank.You will not need to fill up only once (and that would be at the start of your journey) if you need to travel only 99.91 miles (= less than 171 miles).The speed of 55 mph is not part of the solution.
171 miles is 902880 feet. There are 18000 seconds in 5 hours. So in one second, you would travel 50.16 feet, which is just under 50 feet and 2 inches.
