PLEASE HELP IM BEING TIMED A tortoise and a hare raced and the following number were recorded: The tortoise "ran" the entire 100 meter race at a steady pace of 0.2 m/s. The hare started from rest and accelerated at a constant rate of 0.4m/s^2 for the first 30 meters, then rested for 6 minutes, then finished the last 70 meters of the race at a steady speed of 0.5 m/s. How much time (in seconds) did the hare take to complete the race?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
