Rob is setting up a model train track that is 3:
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)
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.
To calculate the number of telephone poles needed, you can use the formula:
Number of telephone poles = Length of track - 1
Given that the length of the track is 3 feet, we can substitute this value into the formula:
Number of telephone poles = 3 - 1
Number of telephone poles = 2
Therefore, Rob will need 2 telephone poles.
To determine the number of telephone poles Rob needs for the model train track, we need to divide the length of the track by the distance between each telephone pole.
Given that the model train track is 3 feet long and a telephone pole is placed every 3 feet, we can set up a simple division equation:
3 feet / 3 feet = 1
Therefore, Rob needs 1 telephone pole for the model train track.
