Baily and Elena compete in a swim race. Their times are shown below. Round each time to the nearest whole second. Then estimate how many seconds Baily won the race by.
The whole second is the first number to the left of the decimal (_.), so : 35.78=36 because 7>5. 39.51=40 because 5=5. 40-36=4. Bailey won the race by about 4 seconds. Hoped I helped!
