Your biking at a speed of 18 miles per hour. your 3 miles behind your friend, who is biking at a speed of 12 miles per hour. write and solve an equation to find the amount of time it takes for you to catch up with your friend

Let us say that:

d = distance of friend

d + 3 = your distance

so that:

d = 12 t

d + 3 = 18 t

Combining the 2 equations:

12 t = 18 t – 3

6 t = 3

t = 0.5 hours

Therefore you catch up after 0.5 hours or ½ hours.

answer: f true

step-by-step explanation:

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.
