I NEED the answer desperately

Question

jessie finished the first race in 2 minutes 7 seconds. Tim finished 12 seconds faster than Jessie. Juan finished 8 seconds faster than Tim. How long did it take Juan to finish?

Answer 1

Hi there Khloe. To solve this problem, let's convert everything into seconds.

Jessie finished in 127 seconds.

Tim finished in (127 - 12) seconds

Juan finished in (127 - 12 - 8 seconds)

To find how fast Juan finished, we subtract 127 - 12 - 8

127 - 12 - 8

115 - 8

107

Juan finished in 107 seconds (1 minute 47 seconds).

Hope that helps!

Answer 2

Jessie = 2min 7sec = 127sec (2min = 120sec)

Tim = Jessie - 12sec = 127sec - 12 sec = 115sec (faster means less time so use subtract)

Juan = Tim - 8sec = 115sec - 8sec = 107sec or 1min 47sec
