If Carly broke the record by 1.3 seconds and Carly's time was 55.7 the old record would be Carly's time plus 1.3 seconds for the time that Carly broke the record by, so... 57 seconds was the old record

Time of old record is 57 seconds for 400 meter.

Given that:

Distance cover by Carly = 400 meter

Time taken by Carly= 55.7 seconds

Difference time from old record = 1.3 seconds less

Find:

Time of old record

Computation:

Time of old record = Time taken by Carly + Difference time from old record

Time of old record = 55.7 + 1.3

Time of old record = 57 seconds
