HELP PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!! Clyde drove 30 miles in 20 minutes and then drove an additional 10 miles in 10 minutes. What is the average speed for the entire trip?

Respuesta :

Add up the number of minutes
20 minutes + 10 minutes = 30 minutes
Add up the number of miles
30 miles + 10 miles = 40 miles
Average speed: 40 miles in 30 minutes.
