30.66 meters per second is 68.58 mph
102.667 feet per second at 70 mph
To convert cm/s to mph, you can use the following formula: 1 cm/s is equal to 0.0223694 mph. So, to convert, multiply the speed in cm/s by 0.0223694 to get the speed in mph.
To convert 750 miles per hour to inches per second, you can use the conversion factors: 1 mile = 63,360 inches, and 1 hour = 3,600 seconds. Therefore, 750 miles per hour is equal to (750 * 63,360) / 3,600 inches per second.
100 mph = 146.6 feet per second.
The easiest way is to convert Miles per Hour to Feet per second. I have the following relationship memorized: 60 MPH = 88 Feet/sec.(35 MPH)/(60 MPH)*(88 Ft/sec) = 51 1/3 Ft/sec. So multiply by 1 sec. and you have 51 1/3 Ft, or 51 feet and 4 inches.
400 mph = 643738 metres per sec (approx) = 10729 metres per minute = 178.82 metres/sec.
2 meters per second = 4.47 mph
1 mile/50 sec * 3600 sec/hr = 72 mph
Mercury - 47.8725 km/sec = 107,000MPH Venus - 35.0214 km/sec = 78,350 MPH Earth - 29.7859 km/sec = 66,630 MPH Mars - 24.1309 km/sec = 54,000 MPH Jupiter - 13.0697 km/sec =29,240 MPH Saturn - 9.6724 km/sec = 21,640 MPH Uranus - 6.8352 km/sec = 15,290 MPH Neptune - 5.4778 km/sec = 12,250 MPH Pluto (TNO, or dwarf planet) = 10,700 MPH
60 mph = 88 ft/sec
14 mph = 20.533 ft per sec
850 mph = 379.98 meters per second.
About 7.6 miles per hour.
Using the ratio of 60 MPH = 88 Ft per Sec Distance = Rate x Time or T = D/R R = 37 MPH (88/60) =or= 54.267 Ft Per Sec T = D/R = 40 Ft / 54.267 Ft per Sec = 0.737 Sec
1 mile = 5280 feet 1 hour = 60 minutes = 3600 seconds 1mph = 1 mile / 1hr = 5280 ft / 3600 sec = 22/15 ft per sec ~= 1.467 ft per sec Therefore to convert mph to ft per sec, multiply by 22/15 (or approx. 1.467).

If you can commit some relationships to memory, it helps. This is one: 60 mph = 88 ft per sec. Divide both sides by 10 --> 6 mph = 8.8 ft per sec. So (600 ft)/(8.8 ft/sec) = 68.182 sec, or 1 minute, 8.182 seconds.
