4.5 x 60/5 ie 54 kph
45 miles.
about 45 mins
3 hours
Speed = Distance/Time so Time = Distance/Speed Time required = 323 / 45 = 7.177.. hours
2 x 45 = 90 miles.
45 mph.
If you could drive non-stop at a constant speed of 45 mph, it would take about 26 minutes and 40 seconds.
The distance between the two towns is 15 miles. This is determined by multiplying the average speed (45 miles per hour) by the time it takes to drive between the towns (20 minutes converted to hours is 1/3 hour). 45 miles/hour x 1/3 hour = 15 miles.
About 1 hour 46 minutes. This is your actual driving time at that speed and does not include stops.
Time = Distance/Speed So time = 150 miles / 45 miles per hour = 3.33.. hours = 3 hours 20 minutes.
At a speed of 50 miles an hour about 4 and a half hours.
If the speed is constant... 5 hours 45 minutes.
