A 70 kg bag of wheat is carried by a boy over a distance of 4 km. If the boy walks at a steady speed of 4 km/h, how much time does it take him to carry the bag?
Answer
1 hour
The correct answer is 1 hour — The result is 1 hour.
Step-by-step solution
- Use the relation time = distance ÷ speed.
- Divide the distance 4 km by speed 4 km/h.
- The result is 1 hour.
Common mistake: Dividing speed by distance instead of distance by speed
Concept tested: Time-distance-speed relation
