Free practice on Time, Distance and Speed for Class 6, following the Cameroon primary school curriculum (English subsystem). Every answer is explained, so a parent who is not sure of the answer can still help.
Speed = Distance ÷ Time. Distance = Speed × Time. Time = Distance ÷ Speed. Remember the triangle: D on top, S and T at the bottom. Cover the one you want.
Keep units consistent. If speed is km/h and time is in minutes, convert minutes to hours first. 30 minutes = 0.5 h. Then distance = speed × 0.5 h.
| Minutes | Hours |
|---|---|
| 15 min | 0.25 h |
| 30 min | 0.5 h |
| 45 min | 0.75 h |
| 90 min | 1.5 h |
