Question

Big Bird decided to visit three of his friends. He got in his car and drove to Elmo’s house. It took Big Bird 10 minutes to drive the 5 miles. After visiting with Elmo for 30 minutes, he headed to Bert and Ernie’s house. This drive covered 15 miles and took 20 minutes. After a 25 minute stay, Big Bird headed to Cookie Monster’s house. The Cookie Monster’s house was 10 miles away and it took Big Bird another 15 minutes to get there. Because Cookie Monster wasn’t home, he was only there for 5 minutes. Big Bird then headed home, a trip that was 20 miles away and took him 25 minutes. What was the average speed for Big Bird’s whole trip (include his visiting time)?

What is average speed?

The average speed of a body is the ratio of the total distance travelled and the time taken to travel that distance.

• Average speed = total distance travelled/time taken

The total distance travelled = 50 miles

total time taken = 130 minutes

Average speed = 50 miles/130 minutes = 0.384 miles/minute.

Therefore, the average speed of Big Bird is 0.384 miles/minute.
