Two trains left the station traveling in opposite directions. the distance train a traveled is modeled by the function d(t)=81t where d represents distance in miles and t represents time in hours. train b traveled a total of 324 miles in 4 hours. how does the distance train a traveled in 1 hour compare to the distance train b traveled in 1 hour? the distance train a traveled in 1 h is equal to the distance train b traveled in 1 h. the distance train a traveled in 1 h is greater than the distance train b traveled in 1 h. the distance train a traveled in 1 h is less than the distance train b traveled in 1 h.

Option A -  The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.

Step-by-step explanation:

Given : The distance Train A traveled is modeled by the function

where d represents distance in miles and t represents time in hours.

To find : How does the distance Train A traveled in 1 hour compare to the distance Train B traveled in 1 hour?

Solution :

Distance traveled by Train A in 1 hour is

Distance traveled by Train B in 1 hour is

or for B, we have 324 miles in 4 hours. If that is at a constant speed, it travels 324/4 = 81 miles in one hour

Therefore, The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.

Hence, Option A is correct.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
