Avery walked for 0.25 miles in 5 minutes. Then she stopped for 5 minutes to meet her friend.After that both of them walked 0.75 miles in 15 minutes.
Again this option is also correct.
Avery walked for 5 minutes at a pace of 20 minutes per mile. Then she stopped for 5 minutes to meet her friend.After that both of them walked for 15 minutes at a pace of 20 minutes per mile.
Because, Time taken to travel 1 mile is 20 minutes.
So, time taken to travel 0.25 miles = 20 * 0.25 = 5 minutes
Time taken to travel 0.75 miles = 20 * 0.75 = 15 minutes
