Use the image above to solve all 4 parts of the question. part 1 - write janet’s time from race #1 in word form. part 2 - three of janet’s times are equal when you round them to the nearest whole second. which three times? part 3 - put janet’s times in order from fastest to slowest. explain how you know. part 4 - grace won race #4 and set a new school record. her time was 1.8 seconds faster than janet’s time for race #4. what was grace’s time? explain how you know.

Step-by-step explanation:

A)

Janet's took 34.56 seconds to cover 50m freestyle swim.

In words it could be said as: thirty four and fifty six hundredths.

B)  

Race #       Time (in sec.)                time( after roundoff to nearest integer)

  1                34.56                                       35

   2                 35                                           35

    3                34.8                                         35

    4                 34.137                                      34

     5                33.92                                       34

Hence, the first 3 race times were equal after rounding off to nearest integer.

C)

on arranging the time of Janet's from fastest to slowest we get the table as:

Race #                              Time( in sec.)

 5                                        33.92

  4                                        34.137

   1                                        34.56

   3                                        34.8

   2                                          35

since, after decimal we arrange the numbers in order same as we do for the natural numbers.

as in race #5 '33' is the smallest among all hence we keep it in first place.

for race 4,1 and 3 we have the same digit before decimals so now we have to look for the number after decimals.

D)

Janet's time in race #4 was: 34.137 sec.

But Grace was 1.8 seconds faster than Janet.

Hence, Grace time=34.137-1.8=32.337 sec.
