Question

8. A race between two competitors Usha and Geeta was conducted in 6 parts. In the first part, Usha won by 10 seconds, then lost by 1 minute in the second part, then won by 20 seconds in the third part, then lost by 25 seconds in the fourth part, next lost by 37 seconds in the fifth part and won by 12 seconds in the last part. Who won the race finally? What values are depicted by the winner? ​

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.
