For a science experiment Marcia dissolved 1.0 Kilogram of sal in 3.0 liters of water. For a different experiment, Bobby dissolved 2.0 pounds of salt in 7.0 pints of water. Which person made a more concentrated salt solution? Explain? Use 1 L = 2.11 pints. Round your answer to the nearest hundredth.
Will a stand hat can hold up to 40 pounds support a 21-kilogram televsion? Explain. Use 2.2 lb = kg.

the first on is 1kg/3L = 0.33333 kg/L
You need to change 2 pounds to Kg
you can use this site for that
then 7 pints to litres 7/2.11 = 3.3175... L
then do the division and compare the answers.
(*You could have done it the other way round if you had wanted to. You just have to make the units the same. )
Tortoise A walks 52.0 feet per hour and Tortoise B walks 12 inches per minute. Which Tortoise travels faster? Explain.
12inces1min=12∗60inches60minutes=12∗60inches60minutes=12∗60inches1hour=(12∗60)/12feet1hour=60feet1hour
so that is faster than 52 feet per hour. :)
