In the second part, she lost by 1 min, then won 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. Who won the race finally?​

Answer 1

Step-by-step explanation:

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.
