3. Let us read this problem.
Jonathan bought a new car. He drove his
car from Manila to Baguio City at an
average speed of 65 kilometers per hour.
For a total of 4.5 hours, how far did he
travel?

8. Speed is a scalar quantity that refers to “how fast
an object is moving”. Speed can be thought of as
the rate by which an object covers distance.
Distance is the total length between two
positions.
Time is the quantity measured or measurable
period during which an action process, or
condition exists or continues.
9. The following is the list of units and their
abbreviations commonly used for speed.
10. A world-record holder ran 800
meters in 86 seconds. What was
his speed rounded to the nearest
tenths?
Answer: The speed of the world record holder was 9.3 m/s
11. A bus travels at a speed of 45
km/hour. How far will it travel in
36 minutes?
Answer: The distance travelled is 27 kilometer.
12. How long will you cover a distance of
300 km at a speed of 60 km per hour?
Answer: Therefore, time needed to cover 300 km is 5 hours.
Do you have a dream car?
What kind of car is it?
In order to have your own car someday, what are you going to do?
a. What is asked in the problem?
b. What are the given data?
c. What equation will be formed?
In order to solve and analyze the problem, we will use the Polya’s Method.
The problem is an example of calculating the distance. The relationship between speed, distance and time can be expressed in the following equations:
Say after the triangle - In everyday life, we usually refer to speed in kilometers per hour (km/h), whereas in a race we use meter per second.
The equation for speed can be remembered from the unit itself: in m/s - m is meter (distance), s is seconds (time). It can, of course, be rearranged to give:
Time= distance over speed
Let’s read and analyze another problem on finding the speed.
Solution:
Given: distance= 800 meters
time= 86 seconds
Using the formula in finding the speed we have: speed= distance divided by time. So, let us substitute the value of distance and time we have distance 800m and time is 86 seconds
Let’s have an example on finding the distance.
Solution:
Given: speed= 45 km/hr
time= 36 minutes
=36/60 Hour (Since we know, 1 hour = 60 minutes)
= 3/5 hour
Using the formula in finding the distance we have: distance = time times speed
May we have another example on finding time.
Solution:
Given: distance = 300 km
speed = 60 km/h
