Atrain travels at a constant speed and has traveled 67. 5 miles in the last 1 1/2 hours. which equation shows the proportion relationship between the distance d, and the time, t, that the train has traveled? a. d=69t b. d=50t c. d=67. 5t d. d=45t

The proportion relationship between the distance d, and the time t, that the train has traveled is, d = 45t. So the correct option is D).

Given :

Train travels at a constant speed and has traveled 67.5 miles in the last 1.5 hours.

Solution :

We know that,

Now the distance (d) traveled by the train in time (t) is,

Therefore, the proportion relationship between the distance d, and the time t, that the train has traveled is, d = 45t. So the correct option is D).

step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
