When running a 100 meter race sergio reaches his maximum speed when he is 40 meters from the starting line, and 6 seconds have elapsed since the start of the race. sergio continues at this max speed for the rest of the race and is 85 meters from the starting line 11 seconds after the start of the race. what is sergio's max speed? meters per second suppose sergio runs for an additional 3 seconds after reaching his max how far will sergio travel during those 3 seconds? meters what is sergio's distance from the starting line 9 seconds after the start of the race? meters what is sergio's distance from the starting line 7.5 seconds after the start of the race? meters

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.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
