How much time does it take for a bird flying at a speed of 45 kilometers per hours to travel a distance of 1,800 kilometers

Step-by-step explanation:

This is simply a case of division. since you already know that the bird is flying at 45 kilometres per hour, you should be able to devise that every hour the bird is going 45km

we are gonna use ratio for this

1:45

?:1800

first of all divide 1800 by 45, to find the number you are gonna multiply the other number by, secondly multiply ur answer by 1 since that is the number of hours it takes to for the bird to travel 45km, after u have suceeded in doing this, you already have ur answer which is 1800 divide by 45 times 1

it’s supposed to be -4+45=41

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
