In a three klometers race Ram beas Shyam by 3 minutes and beats Mohan by 600 meters. If Shyam beats Mohan by 75 seconds in the race, then what is the time taken(In minutes) by Mohan to cover sk klometers? (Assume that Ram, Shyam and Mohan run with uniform speeds)

Answer:
To measure the rate of organismal respiration, a 10mL microrespirometer was constructed. These measure relative volume as oxygen is consumed by respiring organisms. However, as oxygen gas is consumed during aerobic respiration, it is replaced by CO

gas at a ratio of one molecule of CO

for each molecule of O

. However, in the following protocol, the CO

produced is removed by a small piece of cotton treated with potassium hydroxide ( KOH ).
KOH reacts with CO

to form the solid potassium carbonate ( K

). 5mL of germinating pea seeds were placed in one setup while a control microrespirometer was filled with 5mL of glass beads in another. Over the course of 20 minutes, changes in the volume were measured by following the distance of a red soap bubble placed on the end of a 40uL capillary tube at time =0.
If an additional microrespirometer was constructed and placed in a water bath 5
