HELLO, WELCOME BACK TO CLASS
Speed is the distance travelled per Time taken to cover the distance.
Therefore Speed = Distance/ time
taken to cover it.
S = D/T (Km/h, M/S, etc.)
Solved examples on speed distance and time:
- Nancy travelled a distance of 455 km by car in 10 hours. Find the speed of the car.
Distance travelled by car = 455 km
Time taken = 10 hours
Therefore, speed = Distance/Time
= 455/10 km/hr
= 45.5 km/hour
- A car travels a distance of 595 km in 8 ½ hours. What is its speed?
Distance travelled = 595 km
Time taken to travel this distance = 8½ hours = hours
Speed of the car =
= 595/17/2 km/hour
= 592×2/17
= 70 km/hr
Therefore, the speed of the car = 70 km/hour.
ACTIVITY
- Find speed when, distance is 142 km and time is 2 hours
- .Find out the distance covered when, speed is 960 km/hour and time is 1 hour 50 minutes.
- Determine the time taken when, distance is 7150 km and speed is 780 km/hr.
- If distance travelled by a train is 495 km in 4 hours 30 minutes, what is its speed?
- A cyclist covers 950 m in 5 minutes. Find his speed in km/ hour.
- The speed of the train is 72 km per hour. Find its speed in metre per second.
- Express the speed of 60 m per minute in km per hour.
- A man runs at the speed of 10 km/hr. How much time will he take to cover 750 metres?
- Aaron ran 500 metre in 100 Seconds. Find the speed in km per hour.
- A cyclist travels at a speed of 20 km/hour. How far will he travels in 50 minutes?
