Rob is setting up a model train track that is 3:

Question

3
feet long. No telephone pole is needed at the start of the track. However, along the track, he places a telephone pole every
telephone poles does he need? (Input number values only) (3 points)

Answer 1

To determine the number of telephone poles that Rob needs, we have to subtract 1 from the length of the track and then divide by 3.

Length of track - 1 = 3 - 1 = 2
Number of telephone poles = 2 / 3 = 0.67

Since we cannot have a fraction of a telephone pole, Rob will need 1 telephone pole. So, the answer is 1.
