120 km/hr *1000 m/km * 1 hour/60 minutes * 1 minute/60 seconds = 33.333... m/sec
60 sec*60 min= 3600 sec/hr 3600sec/hr *24 hr/day=86400sec/day 86400 sec/day*2 days =172800 sec/2 days there is 172800 seconds in 2 days
Answer 7.6 mph Explanation: 3.4 meters = 0.00211266205 miles So the speed is about .002 miles/second and there are 3600 seconds in a hours. so that is .002x3600=7.2 miles per hour. Now if we use .00211 then we have 7.6 which is a better estimate. 3.4 meters/sec which is about 7.6 mph.
You need to look at a steam table first then Multiply lbs/hr steam x latent heat of evaporation in BTU/lb @ the operating pressure.
32 min 9 sec 40 min 10 sec adding gives... 71 min 19 sec 1 hr 11 min 19 sec. ■
cm/sec, yes? ok, divide by 100 to go from cm to m. then multiply by 3600 to go from sec to hr
73.5 km/hour = 73500 meters/hour = 73500/3600 meters/sec = 20.4166 meters/sec
(350 mi/hr) x (1,609.344 meter/mi) / (3,600 sec/hr) = 156.46 meters/sec (rounded)
(55 km/hr) x (1,000 m/km) / (3,600 sec/hr) = 15.2777 m/s (rounded, repeating)
(66 km/sec) x (3,600 sec/hr) = 237,600 km/hr
Hr/60 mins/60 sec
(50 m/sec) ÷ (1,000 m/km) x (3,600 sec/hr) = 180 km/hr
(9.81 meters/sec) x (3,600 sec/hr) / (1,609.344 meters/mile) = 21.944 mph (rounded)
73.33 feet per second.
(34.2 m/sec) x (3,600 sec/hr) / (1,000 m/km) = 123.12 km/hr (rounded)
(1 km/hr) / [ (1.609344 km/mi) x (3,600 sec/hr) ] = 0.0001726 mi/sec (rounded)Multiply [Km/hr] by 0.0001726 to get [mi/sec] .Or divide it by 5,793.6 .
22 meters/sec = 49.2126 miles/hr (rounded)
