Question

Jodie wanted to match Mandy's obstacle course record of 68.2 seconds. She had already spent forty and one fourth seconds on wall climbing and 12.84 seconds on the ropes. How much time did she have left to match the record?

12.20 seconds
15.11 seconds
53.09 seconds
55.36 seconds

Answer 1

15.11 seconds cause you add forty and one fourths (40.25) and 12.84 and you get 53.09, then you subtract 68.20 with 53.09 and you get an answer of 15.11 seconds
