Answer:
Difference in speed = 10.28 miles/hour
Step-by-step explanation:
Whovenile Delinquents takes 32 minutes to hike up a mountain and 3 minutes to hike down a mountain.
Distance hiked = 3000 feet
We have to find the speed difference of climbing in both the journeys in miles/hour.
Conversions :
- 1 mile = 5280 feet
therefore 3000 feet = 0.57 miles
- 1 hour = 60 minutes
32 minutes = 0.53 hours
3 minutes = 0.05 hours
Speed =
Speed uphill =
Speed uphill = 1.08 miles/hour
Speed downhill =
Speed downhill = 11.36 miles/hour
Difference in speed = 10.28 miles/hour
