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 / 45 MPH * 60 min/hr * 60 sec/min = 80 seconds.
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
