speed limit on highway is 70 miles per hour. find how long it will take to go 105 miles going below or at the speed

Question

The speed limit is on Florida and the travel place is from Orlando to St. Augustine

Answer 1

travel time is distance (miles) / speed (miles/hour)
In the case of 70 mph, time would be 105/70 or 1.5 hours (90 minutes).

A lower speed would take longer. If it was 55 mph, then
time = 105/55 = 1.91 hours (rounded up), or roughly 114.5 minutes
