The distance between town a and town b is 45 kilometers. a) if a train travels at a speed of 60 kilometers per hour, how long will it take to travel from town a to town b? b) if a train takes 40 minutes to travel from town a to town b, what is its speed in kilometers per minute? round your answer to 1 decimal place.

a)

0.8 hours

b)

1.1 kilometers/min

Step-by-step explanation:

a)

D = distance between town A and town B = 45 kilometers

v = speed of the train traveling from town A to town B = 60 kilometers per hour

t = time taken for the train to travel from town A to town B

Time taken is given as

t = D/v

inserting the values

t = 45/60

t = 0.8 hours

b)

D = distance between town A and town B = 45 kilometers

v = speed of the train traveling from town A to town B = ?

t = time taken for the train to travel from town A to town B = 40 minutes

Speed of the train is given as

v = D/t

inserting the values

v = 45/40

v = 1.1 kilometers/min

a) 45 minutes

b)1.1 km per hour

Step-by-step explanation:

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
