A train is traveling at 120 miles per hour. An automatic notification system signals that there is something on the tracks 1200 feet ahead of the train. If the train does not slow down, how long will it be until it hits the obstruction?

the answer is true.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

1875cm³

step-by-step explanation:

we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.

20 × 20 × 5 = 2000cm³

now, we need to calculate the volume of the hole.

5 × 5 × 5 = 125cm³

now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.

2000cm³ - 125cm³ = 1875cm³
