Grant reads a story about a turtle that swam 25 feet in 40 seconds. He assumes the time, t, that it takes the turtle to swim a distance of d feet is a proportional relationship Grant starts to create the table shown for other times and distances the turtle swims.

  30                  18.75

  40                  25

Step-by-step explanation:

We are given table values and they are in proportional relationship.

Time(t)      Distance(d)

  1                   a

  b                   10

  30                  c

  40                  25

Since they are in proportional relationship. Let's form a proportion and missing values (a, b , c) using t = 40 and d = 25.

Cross multiplying, we get

1(25) = a(40)

25 = 40a

a =  

a = 0.625

Now let's find b.

25b = 40(10)

25b = 400

Dividing both sides by 25, we get

b =  

The value of b = 16

Now let's find c.

30(25) = 40c

40c = 750

Dividing both sides by 40, we get

c =  

The value of c = 18.75
