Answer: First option is correct.
Step-by-step explanation:
Since we have given that
Name  Target       Heart Rate Zone
Juan    140 bpm        186 bpm
Tyrell    140 bpm        183 bpm
J.T.      144 bpm        188 bpm
Owen    144 bpm        188 bpm
For Juan, he worked at intensity level of [tex]\dfrac{186}{140}\times 100=132.85\%[/tex]
For Tyrell, he worked at intensity level of [tex]\dfrac{183}{140}\times 100=130.71\%[/tex]
For J.T. and Owen, he worked at intensity level of [tex]\dfrac{188}{144}\times 100=130.55\%[/tex]
On comparing, we get that Juan worked at the highest intensity level.
Hence, First option is correct.
The person who worked the highest intensity level is Juan.
In order to determine who  worked the highest intensity level, we have to determine the ratio of the heart rate zone and the target.
Juan : 186/140 = 1.33
Tyrell : 183 / 140 = 1.31
JT = 188 / 144 = 1.31
Owen : 188 / 144 = 1.31
