Using Formulas

Goal: 1.Plugging numbers into formulas. We use formulas to calculate values. 2.Use the formula d = rt to solve for different values.

Vocabulary Formula – is an equation that shows the relationship between quantities represented by variables. Distance traveled: d = rt (rate X time)  ALL FORMULA PROBLEMS are solved the same way. PLUG what you know into the formula. SOLVE for what you don’t know.

Questions, questions…. How does a track coach figure out how fast someone is….? Distance traveled: d = rt (rate multiplied by time)  ALL FORMULA PROBLEMS are solved the same way. PLUG what you know into the formula. SOLVE for what you don’t know.

Examples Use Distance = Rate times Time to solve.. Distance = Rate x Time (d = rt) Suppose you ride your bike at 10 miles per hour for 3 hours. How far did you bike? We have already done stuff like this! Put the number in for the variable/letter and solve for the ONLY thing left!

Examples Use the provided formula to solve the problem. Distance = Rate x Time (d = rt) Suppose you ride your bike at 8 miles per hour for 4 hours. How far did you bike? We have already done stuff like this! Put the number in for the variable/letter and solve for the ONLY thing left!

Examples Use the provided formula to solve the problem. Distance = Rate x Time (d = rt) Suppose you ride your bike at 12 miles per hour for 2 hours. How far did you bike? We have already done stuff like this! Put the number in for the variable/letter and solve for the ONLY thing left!

Examples Use the provided formula to solve the problem. Distance = Rate x Time (d = rt) Suppose you ride your bike at 5 miles per hour for 10 hours. How far did you bike? We have already done stuff like this! Put the number in for the variable/letter and solve for the ONLY thing left!

Examples Use the provided formula to solve the problem. Distance = Rate x Time (d = rt) Now suppose you rode your bike for two hours and went 18 miles. How fast did you go?

Examples Use the provided formula to solve the problem. Distance = Rate x Time (d = rt) What if you rode your bike for 3 hours and went only 12 miles. How fast did you go?

Examples Use the provided formula to solve the problem. Distance = Rate x Time (d = rt) What if you went 10 miles on your bike and you know you went 5 mph. How long did you ride?

Examples Use the provided formula to solve the problem. Distance = Rate x Time (d = rt) How about you went 21 miles on your bike and you went 3 miles per hour. How long did you bike?

How can you remember how to use Distance = Rate x Time?
