You need to get to class, 200 meters away, and you can only walk in the hallways at about 1.5 m/s. (If you run any faster, you’ll be caught for running.” How much time will it take to get to your class?

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
