The distance a car travels can be found using the formula d=rxt, where d is distance r is the rate of speed, and t id time. if the car had traveled 120 miles in 3 hours, what is the average rate of speed?
a. 30mph
b. 40mph
c. 60 mph
d. 360mph

The correct answer is B. 40 mph

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance (d) the car traveled = 120 miles

Time (t) of the travel = 3 hours

2. What is the average rate of speed?

Rate of speed (r) = Distance (d) the car traveled/Time (t) of the travel

Replacing with the real values, we have:

Rate of speed (r) = 120/3 miles per hour

Rate of speed (r) = 40 miles per hour

The correct answer is B. 40 mph

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.
