What is the formula for calculating speed?
Show answer
Speed = Distance ÷ Time
What is the formula for calculating distance travelled?
Show answer
Distance = Speed × Time
What is the formula for calculating time taken for a journey?
Show answer
Time = Distance ÷ Speed
30 minutes equals ? hours.
Show answer
0.5
15 minutes equals ? hours.
Show answer
0.25
45 minutes equals ? hours.
Show answer
0.75
How do you convert minutes into hours?
Show answer
Divide the number of minutes by 60.
How do you convert a decimal number of hours back into hours and minutes?
Show answer
Multiply the decimal part by 60 to get the minutes.
How do you calculate average speed for an entire journey with different speeds on different sections?
Show answer
Total distance travelled ÷ total time taken
How many metres per second equals 1 kilometre per hour?
Show answer
Approximately 0.278 m/s (or divide km/h by 3.6)
Approximately how many kilometres per hour equal 1 mile per hour?
Show answer
Approximately 1.6 km/h
When calculating average speed, what must you do if time is given in minutes?
Show answer
Convert minutes to hours by dividing by 60 (or convert to the appropriate time unit for the desired speed units).
A bicycle travels at x km/h for 3 hours. What expression gives the total distance in km?
Show answer
3x km (Distance = Speed × Time = x × 3)
To convert km/h to m/s, what calculation do you perform?
Show answer
Divide by 3.6 (or multiply by 1000 to get m/h, then divide by 3600 to get m/s)
When comparing speeds in different units (e.g., mph vs km/h), what must you do first?
Show answer
Convert both speeds to the same unit before comparing them
When calculating journey time with distance in miles and speed in mph, what units will the time be in?
Show answer
Hours (may need to convert to hours and minutes)
If a journey has multiple stages at different speeds, how do you find the total time?
Show answer
Calculate the time for each stage separately (using time = distance ÷ speed), then add all the times together
To check if a car is speeding, what must you calculate from its distance and time?
Show answer
Its actual speed (speed = distance ÷ time), then compare to the speed limit
