The latest thrill ride at a popular theme park takes roller coaster fans on an exciting ride. In the first 20 seconds, it carries its passengers up a 100 meter hill, plunges them 72 meters down and quickly takes them back up a 48 meter rise. How much higher or lower from the start of the ride are they after these 20 seconds?
100 meter hill and then -72 down=28
28+48= 76 meters?
Higher
Right.
You're welcome.

Yes. Are they higher or lower?
