The correct answer is 15:25
Answer:
x = 144
Step-by-step explanation:
y α x
we introduce a constant 'k' when changing from α to =.
i.e y = kx
y = ⅓ when x = 12
Meaning, ⅓ = k * 12
⅓ = 12k
k = ⅓ ÷ 12
k = 1/36
If y = 4, x = ?
using the equation y = kx
4 = (1/36)x
x = 4 ÷ (1/36)
x = 4 * 36
x = 144
The answer is: " 312.5 " .

The pattern given is:
__________________________________________________
" 0.5, 2.5, 12.5, 62.5, ____, ....." ;
Note: The first number in the pattern given is: "0.5" .
"0.5 * 5 = 2.5" ; and "2.5" is the second number in the pattern.
"2.5 * 5 = 12.5" ; and "12.5" is the third number in the pattern.
"12.5 * 5 = 62.5" ; and "62.5" is the fourth number (and final number SHOWN in the pattern).
To find the next number, we multiply "62.5" by "5" ; to get: "312.5" .

The time needed to run the second half of the race is 8.44 s
Step-by-step explanation:
The total distance covered by the athlete during the race is
d = 200 m
And the total time taken to cover this distance is
T = 19.19 s
We also know that the time the athlete needs to cover the first half of the race is
Also, we know that
where 
is the time the athlete takes to cover the second half of the race.
Re-arranging this equation and susbtituting the values, we find the value of t2:
