Vega swam her leg of the race in 27.98 seconds and Janice swam her leg of the relay race in 25.679 seconds. What was their combined time for their part of the relay?

53.659 seconds

Step-by-step explanation:

Given: Vega swam her leg of the race in 27.98 seconds.

Janice swam her leg of the relay race in 25.679 seconds.

Then , their combined time for their part of the relay = (Time taken by Vega) + (Time taken by Janice)

= 27.98 seconds +25.679 seconds

= (27.98+25.679)  seconds

= 53.659 seconds

Hence, their combined time for their part of the relay =  53.659 seconds
