1 min. = 60 sec. 60 min. = 1 hr. 1 hr. = 3600 sec. 24 hr. = 1 day 1 day = 86,400 sec. 7 days = 1 week 1 week = 604,800 sec. 13 weeks = 7,862,400 sec.
45 sec / 1 hr = 45 sec / 3600 sec = 1/80
1 mile/50 sec * 3600 sec/hr = 72 mph
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 mi / 55 MPH = 0.018 hr * 60 min / 1 hr = 1.09 min * 60 sec / 1 min = 1 min 5.5 sec
1 min. = 60 sec. 60 min. = 1 hr. 1 hr. = 3600 sec. 24 hr. = 1 day 1 day = 86,400 sec. 7 days = 1 week 1 week = 604,800 sec. 13 weeks = 7,862,400 sec.

1 mile = 5,280 feet1 hour = 3,600 seconds(1 mi/hr) x (5,280 ft/mi) x (hr/3,600 sec) = (1 x 5,280 / 3,600) (mi - ft - hr / hr - mi - sec) =1.4667 ft/sec (rounded) = 1foot 5.6inches per second
45 sec / 1 hr = 45 sec / 3600 sec = 1/80
1 mile/50 sec * 3600 sec/hr = 72 mph
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 hour 9 minutes 36 seconds. time = distance/speed = 87 miles / 75 mph = 1 4/25 hr = 1.16 hr 1 hr = 60 min → 0.16 hr = 0.16 × 60 min = 9.6 min 1 min = 60 sec → 0.6 min = 0.6 × 60 sec = 36 sec → 1.16 hr = 1 hr 9 min 36 sec
3600 sec / 1 hr = 1
1 mi / 55 MPH = 0.018 hr * 60 min / 1 hr = 1.09 min * 60 sec / 1 min = 1 min 5.5 sec
(100 mi/hr) × (5280 ft/mi) × (1/60 hr/min) × (1/60 min/sec) = 146.67 ft/sec
1 mile = 5,280 feet, and 1 hour = 3,600 seconds (60 mi/hr) x (5,280 ft/mi) x (1 hr / 3,600 sec) = (60 x 5,280 x 1 mi-ft-hr) / (3,600 hr-mi-sec) = 88ft/sec
