Dennis let go of a penny at the top of a well, and the penny fell straight down to the bottom of the well. The top of the well was 1 1/2 meters above ground. the bottom of the well was 11 meters below ground.

the following equation describes the situation

1 1/2 + (-12 1/2) = - 11

what does - 12 1/2 tell us

A) the distance between ground level and the bottom of the well is 12 1/2 meters

B) The distance between the top of the well and the bottom of the well was 12 1/2 meters

C) None of the above

Question

Dennis let go of a penny at the top of a well, and the penny fell straight down to the bottom of the well. The top of the well was 1½ meters above ground. the bottom of the well was 1 meters below ground.

The following equation describes the situation

1½ + (-12½) = 11

what does - 12½ tell us

Answer:

It tells us about the distance between the top of the well and the bottom of the well was 12½

Step-by-step explanation:

When Dennis let go of he penny and the penny went into the well; expectedly, the penny will move straight down to the bottom, provided there's no barrier between the top and the bottom of the well.

If the well is 1½ above the ground and the and the distance between the penny and the ground is calculated as

Distance from top of the well - Depth of well.

Hence, 12½ represent the depth of the well or the distance between the top of the well and the bottom of the well

The answer is B) The distance between the top of the well and the bottom of the well was 12 1/2
