Answer 2

$\textbf {Hey there, here is the solution.}$

.............................................................................................

20 seconds = 2 calories (Given)

.............................................................................................

Convert 3/4 hours into seconds

3/4 x 60 x 60 = 2700 seconds

.............................................................................................

Find the amount of calories burnt:

20 seconds = 2 calories

1 second = 2/20 = 1/10 calories

2700 seconds = 1/10 x 2700 = 270 calories

.............................................................................................

Answer: (D) 270 Calories
