Question

The chart below shows four teammates' target heart rate zones. Their coach had them all using the stair climber each with an average heart rate at 175 beats per minute. Based on this information, who worked at the highest intensity level?
Name Target Heart Rate Zone
Juan 140bpm—186bpm
Tyrell 140bpm—183bpm
J.T. 144bpm—188bpm
Owen 144bpm—188bpm
Juan
Tyrell
J.T.
Owen

Answer 1

Juan, because 186/140 is more than any of the other percentage increases

Answer 2

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 $\dfrac{186}{140}\times 100=132.85\%$

For Tyrell, he worked at intensity level of $\dfrac{183}{140}\times 100=130.71\%$

For J.T. and Owen, he worked at intensity level of $\dfrac{188}{144}\times 100=130.55\%$

On comparing, we get that Juan worked at the highest intensity level.

Hence, First option is correct.
