A squirrel can have a top speed of 20 miles per hour. 

Let h represent the number of hours and m represents the total miles.

A) Create an equation that represents the scenario above.

B) If the squirrel was running for 4 hours straight, then how many miles did it run? Use your equation to solve and state your answer with words.

A) 20h = m  or  m = 20h

B)      20h = m  when h = 4

       20(4) = m

           80 = m

The squirrel will have ran 80 miles after 4 hours.

A squirrel can have a top speed of 20 miles per hour. 

Let h represent the number of hours and m represents the total miles.

A) Create an equation that represents the scenario above.

B) If the squirrel ran 260 miles, then how many hours has it been? Use your equation to solve and state your answer with words.

⭐⭐⭐DOUBLE JEOPARDY⭐⭐⭐

A) 20h = m  or  m = 20h

B)      20h = m  when m = 260

         20h = 260

        ÷20     ÷20

             h = 260 ÷  20

             h = 13

The squirrel will have ran 260 miles after 13 hours.

Natalie has $2.36 and Yarah has X dollars. Together they have a total of T dollars. 

A) Create an equation that represents the scenario above.

B) If Natalie and Yarah have $8.21 all together, then how much money does Yarah have?

A) 2.36 + X = T   or   T = 2.36 + X

B)  2.36 + X = T   when T = 8.21

     2.36 + X = 8.21

        -2.36     -2.36

               X = 8.21 - 2.36

               X = 5.85

Yarah would have $5.85
