Just like any other average. (1) Add the times. (2) Divide the results in this case by 2, since there are 2 different times.
Here is an example: Average of 3:40 and 1:30. Adding the times, you get: 4:70. Convert 60 seconds into one minute, and add to the minutes: 5:10. Divide by 2: half of 5 is 2, remainder 1 minute. (Convert this to 60 seconds again, and add to the remaining seconds. 70 seconds / 2 = 35 seconds, so the final result is 2:35. (In this particular case, you might avoid converting 60 seconds to 1 minute and back again, and thus saved some steps. But you can't always avoid this.)
3.75 min or 3min 45sec.
3min = 180s 180s + 24s = 204s
14 min + 3 min 30 sec _______________ 17 min 30 sec
2 km is equivalent to 2,000 meters. So divide 2,000 by the students speed of 5m/sec. 2,000/5 = 400. So it takes him 400 sec, or 6 2/3min, or 6min 40sec.
To calculate the time it takes to walk 0.18 miles, you need to know the average walking speed. The average walking speed for an adult is around 3-4 miles per hour. Assuming a speed of 3 miles per hour, you can calculate the time it takes to walk 0.18 miles by dividing the distance by the speed: 0.18 miles / 3 mph = 0.06 hours. Since there are 60 minutes in an hour, you would convert hours to minutes by multiplying 0.06 hours by 60 minutes, which equals 3.6 minutes. Therefore, it would take approximately 3.6 minutes to walk 0.18 miles at an average speed of 3 miles per hour.
5 hours and 3min
that depends on how much film you have
3min 20sec
3min. 36sec.
3.75 min or 3min 45sec.
3min 35seconds
It is 300 m per min.
167 MILES. 2hrs and 3min
3min = 180s 180s + 24s = 204s
My guess would be about 3min 47 seconds
less than 10 min. for me it only took 3min
well mine is about my falling and saying random things.... hope you do good! =)
