An elevator ascends at a rate of 29.6 feet per second. If a building is 1,450 feet tall, about how long would it take for the elevator to travel from the ground floor to the roof?

49 seconds

Step-by-step explanation:

Speed is equal to distance/time, therefore time is equal to distance/speed. Given this, that means 1450ft/29.6ft/s=48.98648649, or about 49 seconds to travel from the ground floor to the roof.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
