If you bike for 3 hours at 10 mph and then walk for 1 hour at 2 mph, what would be your average speed?

avg speed=totaldistance/time

total distance=3*10 miles + 1*2 miles= 32miles.
total time=4hours
avg speed=32/4 miles/hr

8 mph

To calculate the average speed, you need to find the total distance traveled and the total time taken.

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.

To find the average speed, you need to calculate the total distance traveled and divide it by the total time taken.

First, let's calculate the distance traveled while biking. The formula for distance is speed multiplied by time:

Distance biked = Speed biked × Time biked
Distance biked = 10 mph × 3 hours
Distance biked = 30 miles

Next, let's calculate the distance traveled while walking:

Distance walked = Speed walked × Time walked
Distance walked = 2 mph × 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 ÷ Total time
Average speed = 32 miles ÷ 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.
