Awesome, thank you everyone for the help!

Oops, I didn't notice that typo. I had it written correctly on my paper, but typed it in wrong here

So I figured out the average speed of the parts of the trip, so I just need to figure out the average speed of the entire trip. So I just plug it into the equation: Average Speed = Distance/Time = (86 km+54 km)/(1.13 hr+1.42 hr) = 54.9 So my final answer would be 54.9 km/hr!

Thank you! I think what you said was what I needed to figure out this problem. So do I have this right: 76 km/h = 54 km/x, which you cross multiply so x=1.13, which means it took 1.13 hrs to drive the first part of the trip Then 38km/hr = 54km/x which makes x = 1.42 So it took 1.42 hours to...

This is where I get stumped. I know it takes one hour to travel 76 km, but I don't know how to calculate how long it will take to travel the extra 10 km to get to 86 km. I know it's probably really simple, but I just don't know how to figure it out.

I know speed=distance/time So time=distance/speed

Homework Statement So here's a problem I need help with for my physics class that's due tomorrow night. On a road trip, a driver achieved an average speed of 76 km/h for the first 86.0 km and an average speed of 38 km/h for the remaining 54.0 km. What was her average speed (in km/h) for the...

Hello there! I'm a new member here and chanced upon this website while looking for help with a physics problem. After looking around I figured this would be a good place to join so I could get help with my physics homework. I'm a junior in college and it's required for me to take this intro...
