Length of the whole trip = D km
Unknown speed for the second half = X km/hr
Time for the first half = (D/2)/67 = D/134 hours
Time for the second half = (D/2)/x = D/(2x) hours
Total time for the trip = (D/134) + (D/2x) = D/86
1/134 + 1/2x = 1/86
2x/134 + 1 = 2x/86
x/67 + 1 = x/43
x(1/43 - 1/67) = 1
x = 1 / (1/43 - 1/67) = (43 x 67) / (67 - 43) = 2881/24 = 120.042 km/hr (rounded)
=============================================
Check:
(1/134) + (1/240.084) = (240.084 + 134) / (240.084 x 134) = 1/86 QED yay !
The first running average is the first grade. The second running average (RA) is the average of the first two grades, the third RA is the average of the first three grades and so on.
Lucy's family drove 463 km on the first day and 421 on the second day. What was the average distance in a day
On average u should know them in first or second grade !
Simply divide 34 by 4 and you get 8.5, which is the second number and the first number must be three times 8.5, which is 25.5
Calculating an average is done in two steps: - First: you calculate the sum of the terms whose average you would like to calculate. - Second: you divide the sum of the terms by their number. In your case: - First: 10 + 6 + 12 = 28 - Second: 28 / 3 = 9.33333.... 3 is the number of terms added together which are: 10, 6 and 12 (3 numbers). Answer: Therefore your average is: 9.33333....
Nobody knows for sure who was even the FIRST to achieve flight.
Normally the second removable drive, A = first removable or floppy drive, if a second floppy drive is installed it is drive B. First hard disk is Drive C, second Hard disk is Drive D, etc. You can also map the drive letters to the virtual network connections, so that Drive P could be used as a network connection.
The exact same thing as the first drive axle.
