30 minutes or half an hour.
73 / A = hours of travel time
Divide the distance by the speed.
at what speed?
It takes (68 hours) divided by (the speed you travel, in miles per hour).
That depends on the speed. Pick a suitable speed, in miles/hour, then divide the distance by the speed. The answer will be in hours.
12 hours 41 minutes.
14 hours 44 minutes.
At 30 kph, it would take 1 hour. At 60 kph, it would take 1/2 hour.
2.4/30 = 0.08 hour = 4minutes 48seconds
15,000 hours
About 1 hour 41 minutes. This assumes you travel at a constant speed with no stops.
Use the basic formula for speed: distance = speed x time
