Problema Solution
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?
Answer provided by our tutors
100-meter rise, 72-meter descent followed by a 48-meter rise
100-72+48 = 76
after these 20 seconds, they are 76 meters higher than at the start of the ride
