Ursula drives 100 km from Blueville to Red City. The road from Blueville to Greentown has a speed limit of 80 km/h, while the road from Greentown to
Red City has a speed limit of 60 km/h. If it takes her 1.5 hours to get from
Blueville to Red City, how long is the trip between Blueville and Greentown?
Can I receive some help, please? Thank you!
