Based on the information that was given in the table, the time taken for 1 kilometer will be 16 minutes.
From the question, the time taken for 5 kilometers is 40 minutes while the time taken for 7 minutes is 52 minutes.
This can be solved using arithmetic progression. This will be:
a + 4d = 40
a + 6d = 52
Subtract the equations
2d = 12
d = 12/2
d = 6
Therefore, a which is the first kilometer will be:
a + 4d = 40
a + 4(6) = 40
a + 24 = 40
a = 40 - 24
a = 16
Therefore, the time taken for 1 kilometer is 16 minutes.
