Kimberly weighs 150 pounds and exercised on a cycle ergometer for 27 minutes at a steady-state workload of 60 rpm with a 1.5 kp resistance. Kimberly's average VO2 was 2.24 LO2/min and her average VCO2 was 2.01 LCO2/min. Assuming that 1 revolution on the ergometer is equal to 6 meters, calculate Kimberly's net mechanical efficiency during this bout of exercise. Round your answer to the first decimal place.

A. 12.61%
B. 11.3%
C. 13.7
D. 10.1%

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
