CONTENT OF THE LESSON
LESSON ONE – INTRODUCTION TO SPEED
Pupil’s Activities 1 – Compare Speed of Two or More Motors

Teacher’s remark – The choice of means of transportation especially land transportation is greatly determined by speed and time takes to reach various destinations.
Teacher’s/Pupil’s Activities 2 – Speed and Time Taken
Speed is often measured in kilometres per hour (minute) or meters per second. This is written for short as km/h(m) or m/s. To find the average speed, you divide distance covered by time taken.
That is: Average speed =
- A car takes 3 700 km in 5 hours. What is its average speed?
Distance = 3 700 km
Time = 5 hours
Average speed = 3 700 km /5 h
= 740 km/h
- Ayomide walked a distance of 180 metres in 5 seconds. Find his average speed.
Average speed = 180 m/5 s = 36 m/s.
Pupil’s Activities 2 – Class Exercise/Take Home
1. If it takes 3 hours to drive a distance of 210 km on a motorway, what would be your average speed in km/h?
2. A train travelled 10 080 km in 12 hours. Find its average speed.
LESSON TWO – WORK IN PROGRESS
To deliver the lesson, the teacher adopts the following steps:
1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;
2. Guides pupils to calculate average speed as distance covered over time.
Pupil’s Activities – Calculate average speed using distance covered over time.
3. Guides pupils to solve quantitative aptitude problems related to time and speed.
Pupil’s Activities – Solve quantitative aptitude problems related to time and speed.
To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
Pupils to calculate speed when time and distance are given.
