Question

An elevator travles 310 feet in 10 seconds. at that speed, how far can this elevaor travles in 12 seconds? explain your reasoning.

Answer 1

Step-by-step explanation:

We can do cross multiplying through ratios:

310 feet / 10 secs = x feet / 12 secs

10x = 310 * 12

10x = 3720

x = 372 feet

OR

Divide 310 feet and 10 secs to get 31 feet in 1 sec

Multiply 31 ft and 1 sec to get 372 ft in 12 secs
