Card 1Speed calculation

Solve: A boy walks 300 m in 2 minutes. Find his speed in m/min.

Answer

Step 1: Use Speed = Distance / Time. Step 2: Speed = 300 m / 2 min. Step 3: Speed = 150 m/min. Answer: 150 m/min.

Card 2Speed calculation

Solve: A boy walks 300 m in 2 minutes. Find his speed in m/s.

Answer

Step 1: Convert time to seconds. 2 minutes = 120 seconds. Step 2: Use Speed = Distance / Time. Step 3: Speed = 300 m / 120 s = 5/2 m/s. Step 4: 5/2 m/s = 2.5 m/s. Answer: 2.5 m/s.

Card 3Speed calculation

Solve: A man covers 3.6 km in 24 min. Find his speed in km/h.

Answer

Step 1: Convert 24 min to hours. 24 min = 24/60 h = 2/5 h. Step 2: Use Speed = Distance / Time. Step 3: Speed = 3.6 km / (2/5) h. Step 4: Speed = 3.6 × 5/2 = 9 km/h. Answer: 9 km/h.

Card 4Speed calculation

Solve: A man covers 3.6 km in 24 min. Find his speed in m/s.

Answer

Step 1: Convert distance to metres. 3.6 km = 3600 m. Step 2: Convert time to seconds. 24 min = 1440 s. Step 3: Use Speed = Distance / Time. Step 4: Speed = 3600 / 1440 = 5/2 m/s. Step 5: 5/2 m/s = 2.5…

Card 5Key formula

Formula for speed

Answer

Speed = Distance / Time. Use metres and seconds together for m/s, or kilometres and hours together for km/h. Quick example: 3600 m in 1200 s gives speed = 3600 / 1200 = 3 m/s.

Card 6Unit conversion and speed

Solve: A car covers 375 m in 25 s. Find its speed in km/h.

Answer

Step 1: Use Speed = Distance / Time. Step 2: Speed = 375 m / 25 s = 15 m/s. Step 3: Convert m/s to km/h by multiplying by 18/5. Step 4: 15 × 18/5 = 54 km/h. Answer: 54 km/h.

Card 7Unit conversion

When do you use the conversion 1 km/h = 5/18 m/s?

Answer

Use it when speed is given in km/h and the answer is needed in m/s. Worked example: 72 km/h × 5/18 = 20 m/s. So, 72 km/h = 20 m/s.

Card 8Unit conversion

When do you use the conversion 1 m/s = 18/5 km/h?

Answer

Use it when speed is given in m/s and the answer is needed in km/h. Worked example: 15 m/s × 18/5 = 54 km/h. So, 15 m/s = 54 km/h.
