There are six lots of ten minutes in an hour, so 1 mile per 10 mins is the same as 6 miles per hour.
To convert feet per second to miles per hour, first convert feet to miles. There are 5280 feet in a mile. So, 8.5 feet per second = 8.5 * 3600 seconds in an hour / 5280 feet in a mile = 5.78 miles per hour.
You thought fractions would never be good for anything! Forget the numbers and concentrate on the units: 60 miles -------- 1 hour What would you multiply this by to cancel the hours? 60 miles hours miles -------- x ----- = ----- 1 hour sec sec What is hours/second? There are 3600 seconds in 1 hour so hours/second = 1 hour/3600 seconds which means: 60 miles 1 hour 60 miles -------- x -------- = -------- 1 hour 3600 sec 3600 sec Now, what would you multiply miles/sec by to get feet/sec? 60 miles feet feet -------- x ---- = ---- 3600 sec mile sec What is feet/mile? There are 5280 feet in 1 mile so feet/mile = 5280 feet/1 mile which means: 60 miles 5280 feet 60 x 5280 feet -------- x --------- = -------------- 3600 sec 1 mile 3600 sec 60 x 5280 = 316800 ----------- 3600 then dived the bottom into the top and you get your answer. This works for any conversion. You just multiply the fractions that are appropriate and you end up with the answer. Sixty miles per hour works out at 88 feet per second. This question seems more like math homework then about motorcycle safety...
There are no miles in 75 kilometers per hour, it is a measure of speed and not distance. To convert 75 kilometers per hour to miles per hour, you can use the conversion factor: 1 kilometer is approximately 0.621 miles. So, 75 kilometers per hour is approximately 46.6 miles per hour.
To convert a time in seconds to miles per hour, you first need to convert the distance to miles. 40 yards is approximately 0.02273 miles. Then, you can calculate the speed by dividing the distance by the time in hours. For 4.3 seconds over 40 yards, the speed is approximately 1.25 mph.
You should allow at least 4 seconds of following distance when driving a 30-foot vehicle at 55 mph. This provides enough time to react to any sudden changes in traffic ahead and helps prevent rear-end collisions.
12.41 mph
60 mph(1 mile/60 sec)*(60 sec/1 min.)*(60 min/hr)
1 mile/50 sec * 3600 sec/hr = 72 mph
1 mi / 55 MPH = 0.018 hr * 60 min / 1 hr = 1.09 min * 60 sec / 1 min = 1 min 5.5 sec
60 sec = 1 minute 60 min = 1 hour 3600 sec = 1 hour one mile/sec = 3600 mph - pretty fast!
This would be an average speed of 8.1 miles per hour.
1 mi / 70 mph = .014 hr = .857 min = 51.43 sec.
60 sec = 1 min 60 min = 1 hr 40 sec = 40/60 min = 2/3 min 2 min 40 sec = 22/3 min = 8/3 min → 2 min 40 sec = 8/3 ÷ 60 hr = 8/3 x 1/60 hr = 2/45 hr speed = distance ÷ time = 15/8 mi ÷ (2 min 40 sec) = 13/8 mi ÷ (2/45 hr) = 13/8 x 45/2 mi/h = 585/16 mph = 369/16 mph ≈ 36.5 mph
1 mi / 45 MPH * 60 min/hr * 60 sec/min = 80 seconds.
1 mi / 65 mph = .015 hr = .923 min = 55.4 sec.
60 mi/hr * 1 hr/60 min * 1 min/60 sec * 5280 ft/mi = 88 ft/sec; so 60 MPH is 88 ft/sec. Multiply 88 ft/sec * 6 sec = 528 ft.
1 min = 60 sec 1 hour = 60 min = 60 × 60 = 3600 sec → 1 sec = 1/3600 hr distance = speed × time = 45 mph × 1 second = 45 mph × 1/3600 hr = 45 × 1/3600 miles = 1/80 mile = 1 chain = 22 yards = 66 feet
