The value of y is directly proportional to the value of x. If y = 180 when x = 50, the value of y when x = 25?

When two numbers or quantities are Directly proportional to each other, their ratio is constant or we can write is as:

Step-wise-Step Explanation:

According to the relation between two numbers which are directly proportional to each other:

⇒ x1 / y1 = x2 / y2

Plugging the given values:

⇒ 50 / 180 = 25 / y2

Cross multiplying,

⇒ y2 = 180 × 25 / 50

⇒ y2 = 90

Thus, value of y when x = 25 is 90.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

pretty sure 750 each month!
