Question

Round each time to the nearest whole second. Then estimate how many seconds bailey won the race by.

Answer 1

Bailey won by 4 seconds because if you round her score it would be 36 and Elenas score is 40.

Answer 2

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!
