Calculator Functions

Function	What it does	What it requires
Distance	Finds how far a trip goes at a steady speed	Requires the average moving speed and the moving time
Average moving speed	Finds the speed in miles per hour from a distance and a time	Requires the distance and the moving time
Moving time	Finds how long a distance takes at a steady speed	Requires the distance and the average moving speed

Speed can be entered in mph, km/h, m/s or ft/s, time in minutes, hours or seconds, and distance in miles, kilometers, meters or feet. Each result is also shown in kilometers and km/h, as a pace in minutes per mile, and at the quarter, half and three-quarter points of the trip. Planned stops in minutes are optional. They are added to the elapsed time and do not change the distance.

Miles Per Hour to Distance Formulas

Other units are converted first, with 1 mile = 1.609344 km exactly and 1 mph = 1.609344 km/h [1].

Distance

The main formula applies directly. At 60 mph for 2 hours the distance is 60 × 2 = 120 miles. At 45 mph for 20 minutes it is 45 × 20 ÷ 60 = 15 miles.

Average moving speed

Miles per hour is the distance in miles divided by the time in hours. A trip of 40 miles in 15 minutes is 40 ÷ 0.25 = 160 mph, and 150 miles in 2.5 hours is 60 mph.

Moving time

The time in hours is the distance divided by the speed. At 60 mph, 300 miles takes 300 ÷ 60 = 5 hours of driving, and 30 minutes of planned stops makes the trip 5 hours 30 minutes. The table gives the moving time for common distances.

Distance	At 30 mph	At 55 mph	At 60 mph	At 70 mph
15 mi	30 min	16 min	15 min	13 min
30 mi	1 h 00 min	33 min	30 min	26 min
60 mi	2 h 00 min	1 h 05 min	1 h 00 min	51 min
100 mi	3 h 20 min	1 h 49 min	1 h 40 min	1 h 26 min
124 mi	4 h 08 min	2 h 15 min	2 h 04 min	1 h 46 min
140 mi	4 h 40 min	2 h 33 min	2 h 20 min	2 h 00 min
191 mi	6 h 22 min	3 h 28 min	3 h 11 min	2 h 44 min
500 mi	16 h 40 min	9 h 05 min	8 h 20 min	7 h 09 min
1,000 mi	33 h 20 min	18 h 11 min	16 h 40 min	14 h 17 min
1,400 mi	46 h 40 min	25 h 27 min	23 h 20 min	20 h 00 min
2,000 mi	66 h 40 min	36 h 22 min	33 h 20 min	28 h 34 min

Limits of This Estimate

• The speed is treated as a steady average over the whole moving time. Traffic, speed limits and slowing for turns lower the real average below the cruising speed.
• Stops are added as a single total, so the checkpoint times show moving time only.
