avg speed=totaldistance/time
total distance=3*10 miles + 1*2 miles= 32miles.
total time=4hours
avg speed=32/4 miles/hr
total distance=3*10 miles + 1*2 miles= 32miles.
total time=4hours
avg speed=32/4 miles/hr
First, let's find the total distance traveled during each activity:
Distance biked = speed x time = 10 mph x 3 hours = 30 miles
Distance walked = speed x time = 2 mph x 1 hour = 2 miles
Next, let's find the total time taken:
Total time = biking time + walking time = 3 hours + 1 hour = 4 hours
Finally, we can calculate the average speed:
Average speed = total distance / total time = (30 miles + 2 miles) / 4 hours = 32 miles / 4 hours = 8 mph
Therefore, the average speed would be 8 mph.
First, let's calculate the distance traveled while biking. The formula for distance is speed multiplied by time:
Distance biked = Speed biked ร Time biked
Distance biked = 10 mph ร 3 hours
Distance biked = 30 miles
Next, let's calculate the distance traveled while walking:
Distance walked = Speed walked ร Time walked
Distance walked = 2 mph ร 1 hour
Distance walked = 2 miles
To find the total distance, add the distance biked to the distance walked:
Total distance = Distance biked + Distance walked
Total distance = 30 miles + 2 miles
Total distance = 32 miles
Now, let's calculate the total time taken:
Total time = Time biked + Time walked
Total time = 3 hours + 1 hour
Total time = 4 hours
To find the average speed, divide the total distance by the total time:
Average speed = Total distance รท Total time
Average speed = 32 miles รท 4 hours
Average speed = 8 mph
Therefore, the average speed of biking for 3 hours at 10 mph and then walking for 1 hour at 2 mph would be 8 mph.
