30.66 meters per second is 68.58 mph
I have this relationship memorized: 60 mph = 88 feet/sec.(750 mph)/(60 mph)*(88 ft/sec)*(12 in/ft) = 13200 inch/sec
== 0.000946969697 mph
102.667 feet per second at 70 mph
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.
100 mph = 146.6 feet per second.
I have this relationship memorized: 60 mph = 88 feet/sec.(750 mph)/(60 mph)*(88 ft/sec)*(12 in/ft) = 13200 inch/sec
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
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).
