Daisy is going 12 mph and sally is going 8 mph if they where 60 miles apart how many hours would it take for them to meet up

3 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed in mph

d -----> the distance in miles

t ----> the time in hours

x ----> distance traveled by Daisy to the meeting point

60-x ----> distance traveled by Sally to the meeting point

so

Solve for d

Distance traveled by Daisy to the meeting point

we have

substitute

----> equation A

Distance traveled by Sally to the meeting point

we have

substitute

----> equation B

substitute equation A in equation B

solve for t

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.

the radius is 2 times the diameter.
