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

What does the phrase light year mean?
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
How do you calculate the speed of light in centimeters per hour?
The speed of light is approx 300,000 km/sec. That is 300,000*100,000 cm per sec = 3.0*1010 cm per second = 3.0*1010 *60*60 = 1.08*1014 cm per hour.
Would you use less electrical energy burning a 60 watt light bulb for 900 seconds or a 100 watt light bulb for 500 seconds?
1 watt = 1 Joule/sec 60 watts x 900 sec = 54 000 Joule 100 watts x 500 sec = 50 000 Joule So you use less electrical energy using 100 watt light bulb for 500 seconds.
What distance does a vehicle travel in 1 second if doing 35 mph?
The easiest way is to convert Miles per Hour to Feet per second. I have the following relationship memorized: 60 MPH = 88 Feet/sec.(35 MPH)/(60 MPH)*(88 Ft/sec) = 51 1/3 Ft/sec. So multiply by 1 sec. and you have 51 1/3 Ft, or 51 feet and 4 inches.
Convert 2310 seconds to hours?
2310 sec * 1 min/60 sec * 1 hr/60 min is 0.642 hr.
How long does it take light to travel from the sun to Saturn in units of sec?
Saturn is about 75 light-minutes from the Sun, so multiply that by 60 to get light-seconds.
How many feet will you travel going 60 mph in 6 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.
How far do you travel at 60 mph in 1 sec?
88 feet, which is one sixtieth of a mile, as you would be travelling one mile per minute.
How far do you travel at 45 mph in 1 sec?
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
How fast must you travel to go 990 feet in 1 sec?
Clear your units. 990ft/sec * 60 sec/minute * 60 min/hour = 3,564,000miles/hour or 3.564x10^6 miles per hour.
How fast nerve signals travel to the brain per sec?
Nerve speeds vary, BUT on average move 115-197 ft/sec (35-60 m/sec).
How far does light travel in 30 seconds?
The speed of light is approximately 3 x 10^8 metres/sec. So in 10 minutes, light would travel 60 time that which is 180 x 10^8 metres or 18,000,000,000metres or 18 million km.

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
How many miles can a commercial jetliner flying at 253 meters per second travel in 6 hours?
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.
If you travel 55 miles per hour how many minutes will it take to travel one mile?
1 mi / 55 MPH = 0.018 hr * 60 min / 1 hr = 1.09 min * 60 sec / 1 min = 1 min 5.5 sec
How do you write a c program to convert time in sec to time?
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); }
How far will you travel in 3 minutes running at a rate of 6 meters per second?
3 minutes = 3 * 60 = 180 seconds. 180 seconds * 6 meters/sec = 1080 meters.
