Question: From her science class study, Brady learned that each whale in the sea has 40 gallons of blood. She also learned that a shark has three times as much blood as a whale. Calculate the number of gallons of blood that ten sharks swimming in the sea have.
Give me a solution to this problem
Answer: 
Since a shark has three times as much blood as a whale, then a shark has 3*40 = 120 gallons of blood.
10 sharks swimming in the sea will have 10*120 = 1200 gallons of blood.
