At the last, According to the linear equation, Fatima won the race.
According to the statement
We have to find that the who won the race.
So, For this purpose, we know that the
A linear equation only has one or two variables.
From the given information:
Sana won by 10 seconds. In the second part she lost by 1 minute, then word by 20 seconds in the third part and lost by 25 seconds in the fourth part, she lost by 37 seconds in the fifth part and won by 12 seconds in the last part.
Then
Let winning time be a positive integer and losing time is a negative integer, as it is opposite of winning.
1 minute = 60 seconds
Therefore, Sana’s total difference time with Fatima
=10−60+20−25−37+12
=42−122
=−80 Seconds
Therefore, Sana lost the race by 80 seconds or by 1 min 20 seconds.
Which means Fatima, won the race.
So, At the last, According to the linear equation, Fatima won the race.
