Final answer:
Wangchuk, who previously walked 10 km in 1 hour, would take approximately 5 minutes to walk 833 m at the same speed, even though this is not one of the provided options.
Step-by-step explanation:
The student's question is about calculating the time it will take for Wangchuk to cover a shorter distance at the same speed he previously walked. Wangchuk walked 10 km due west in 1 hour. To find out how long it will take to walk 833 m due west at the same speed, we can use the equation: time = distance/speed. Since we know the distance (833 m or 0.833 km) and we can calculate the speed (10 km/h), then time = 0.833 km / 10 km/h = 0.0833 hours.
To convert hours to minutes we multiply by 60, thus 0.0833 hours * 60 minutes/hour = approximately 5 minutes. However, this is not one of the provided options, which suggests there may have been a typo or an error in the question or the options. If we ignore the provided options and go with the accurate calculation, the correct time would be 5 minutes.
