its known that the speed of light is =3 x 108 m/s
and speed=distance/time distance=speed x time
=3 x 108 m/s x 60
=18 x 109 metres
its also known that 1000m=1kilometre
18 x 109 metres=18 x 106 kilometres
hence distance travelled by light in 60 seconds is 18 x 106 kilometres in vaccuum
a lightyear is a measure of distance that is the distance light will travel in one year. yes also it can travel in 24 hours
9,460,730,472,580.8 km Light travels at 299,792.458 km/sec. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year. Multiply all those together to get the distance that light travels in one year.
Mercury is about 57,500,000 kilometers (36,000,000 miles (36 million miles)) from the Sun, Earth is about 152,000,000 (93,000,000 miles (93 million miles)) - a little less than 3x farther away. Since it takes about 9 minutes for light to get to Earth from the Sun, it stands to reason it would take about 3 minutes to get to Mercury from the Sun.Light to Earth152,000,000,km/300,000km/s ~ 506 secs, 506secs x 1 min/60 secs ~ 8.5 mins(93,000,000 miles/ 186,292 miles per second ~ 499 seconds, 499 seconds x 1 min/60 seconds ~ 8.3 mins, )Light to Mercury57,500,000 kilometers/300,000km/sec ~ 192 sec, 192 sec x 1 min/60 secs ~3.2 mins(36,000,000 miles/186,292miles/sec ~ 193 sec, 193 sec x 1 min/60 secs ~ 3.2 mins)
It would use less electrical energy to burn the 60 watt light bulb for 900 seconds. This is because the total energy consumed is calculated by multiplying the power (in watts) by the time (in seconds), so for the 60 watt bulb: 60 watts * 900 seconds = 54,000 watt-seconds, and for the 100 watt bulb: 100 watts * 500 seconds = 50,000 watt-seconds.
What do you want to convert it to ??Example: Convert [ 'Q' km per second ] to [ miles per minute ].Use:(60 sec/min) = 1(1 mile/ 1.609344 km) = 1(Q km/sec) x (60 sec/min) x (mile/1.609344 km) = (Q x 60/1.609344) x (km-sec-mile/sec-min-km)= 37.2823 Q mile/min
Saturn is about 75 light-minutes from the Sun, so multiply that by 60 to get light-seconds.
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.
88 feet, which is one sixtieth of a mile, as you would be travelling one mile per minute.
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
Clear your units. 990ft/sec * 60 sec/minute * 60 min/hour = 3,564,000miles/hour or 3.564x10^6 miles per hour.
Nerve speeds vary, BUT on average move 115-197 ft/sec (35-60 m/sec).
1 min = 60 sec 1 hour = 60 min = 60 × 60 sec = 3600 sec 1,609.344 m = 1 mile (exactly) It will travel: Distance = speed × time = 253 m/s × 6 hours = 253 m/s × 6 × 3600 s = 5,464,800 m = 5,464,800 ÷ 1,609.344 miles ≈ 3,395.70 miles.
main() { int sec=00,min=00,hr=00; printf("Enter time in seconds"); scanf("%d",&sec); if (sec<60) printf("%d :%d : %d",hr,min,sec); else if(sec>=60) min=int(sec/60); sec=int(sec%60); printf("%d: %d : %d",hr,min,sec); else if (sec>=3600) min=int(sec/60); sec=int(sec/60) hr=int(min/60); printf("%d : %d : %d",hr,sec,min); }
1 mi / 55 MPH = 0.018 hr * 60 min / 1 hr = 1.09 min * 60 sec / 1 min = 1 min 5.5 sec
Hr/60 mins/60 sec
1 min = 60 sec Hence 1 sec = 1/60 min
To travel 200 miles at 450 mph takes 26 min 40 sec. time = distance / speed = 200 miles / (450 miles / hour) = 4/9 hour ≈ 0.444 hour 1 hour = 60 min → 4/9 hour = 4/9 × 60 min = 26 2/3 min ≈ 26.667 min 1 min = 60 sec → 2/3 min = 2/3 × 60 sec = 40 sec
