Question

Starting at home, Jessica traveled uphill to the grocery store for 18 minutes at just 20 mph. She then traveled back home along the same path downhill at a speed of 60 mph

Answer 1

Answer:

The average speed is 30 mph, and which is closer to 20 mph than 60 mph as we expected.

Step-by-step explanation:The average speed is not just the average of 20 mph and 60 mph.

She traveled for a longer time uphill (since she was going slower), so we can estimate that the average speed is closer to 20 mph than 60 mph.
