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.
