Question:

A charter bus travels 225 miles in  4.5 hours. Assume the  distance travelled is directly  proportional to the time spent.

Write a direct variation equation.

Step-by-step explanation:

Let:

y =  distance

x = time

So:

 and

Since, they are directly proportional: The following relationship exists

Where

k = constant of variation

Substitute values for y and x

Make x the subject

Substitute 50 for k in

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
