✍️ Practice
1. Speed = Distance ÷ Time
120 km in 2 h. Speed (km/h) =
90 km in 3 h. Speed =
200 km in 5 h. Speed =
240 km in 3 h. Speed =
2. Distance = Speed × Time
15 km/h × 4 h =
50 km/h × 6 h =
80 km/h × 2 h =
80 km/h for 30 min =
3. Time = Distance ÷ Speed
Answer in hours.
100 km at 25 km/h =
60 km at 20 km/h =
200 km at 40 km/h =
100 km at 50 km/h =
4. Temperature basics
Water freezes at __ °C
Water boils at __ °C
Body temp ≈ __ °C
°C stands for __
5. Temperature change
35°C − 18°C =
22°C → 30°C, change =
40°C − 28°C =
25°C − 10°C =
6. Real-world
Walk 4 km/h for 3 h. Distance =
Plane: 600 km in 2 h. Speed =
Train at 60 km/h covers 180 km in __ h
Bahrain summer noon ≈ __ °C
