If the total time is 120 seconds and the total distance is 320 meters. Calculate the average speed (show work)

S=D/T

320/120= 2.66 miles

Explanation:

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

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.
