Answer:

4.752calories

Explanation:

135 pounds = 61.24kg

3.7 mph = 1.65405m/s x 60

= 99.243m/min

Oxygen used = 0.2*speed + 0.9*speed*grade + 3.5

=0.2*99.243 + 0.9*99.243*0.1 + 3.5

= 31.68

Dividing by 200 get calories expenditure per minute = 0.1584

Calroies burned = 0.1584 x 30

= 4.752Calories.
