When someone says it's "twenty of", he/she means it is twenty minutes before an implied hour. For example, twenty of six is 5:40, twenty of seven is 6:40, twenty of eight is 7:40, etc.
By putting them in boiling water for a certain amount of time (say 20 minutes or so).
Well you have 60 seconds and 20 minutes so 60x20 soo 1,200 1,200
It takes about 8 minutes 20 seconds for light from the Sun to reach the Earth.
An airplane travels 80 km in 10 minutes and then flies 100km in 20 minutes the average speed of the plane is? 80 km in 10 minutes = 8 km/min 100km in 20 minutes = 5 km/min Average speed = total distance traveled ÷ total time Average speed = 180 km ÷ 30 min = 6 km/minute Notice the average speed is closer to 5 km/min, because the plane spends twice as much time traveling at the slower speed.
If you could run a four-minute mile (a nearly record time), that would be 20 miles in eighty minutes. So the answer is no.
Time is relative. Therefore, if you take 20 minutes to walk 200 yards then 20 minutes is a long time. However, relative to an average lifetime, 20 minutes is a very short amount of time.
Time = Distance/Speed So time = 9 miles / 20 mph = 9/20 hours = 60*9/20 minutes = (60/20)*9 minutes = 3*9 minutes = 27 minutes.
20 minutes
Her travel time is three hours and 20 minutes, because the 20 minutes is added to the non-stop time described.
It is a time which is 260 minutes after the first.
As of 2015, there are two halves of 20 minutes each. (Clock time excluding stoppages of play.)
60 minutes = 1 hour → 20 minutes/lb x 20 lb = 400 minutes = 400 ÷ 60 minutes = 6 hours 40 minutes. [Cooking time would be 7 hours, as an extra 20 mins is [usually] added.]
81 minutes = 1 hour and 20 minutes = 4,860 seconds
