If a snail travels at 5 m/s, how far will it travel in 90 seconds?

d = 450 m

Explanation:

                                   d

use the formula   v =

                                   t

v = 5 m/s

t = 90 seconds

                d

5 m/s =

             90 sec

d = 5 m/s ( 90 sec)

d = 450 m

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.
