2 Ajar contains 840 ml of water. All the water in the jar is poured into two glasses so that the ratio of the volume of water in the first glass to that in
the second glass is 2:5. How much water is there in each glass? Please help

240ml in first jar and 600 ml in second jar

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
