Question

Suppose a certain series of gymnastic moves takes 35 seconds to complete. If a gymnast does that series seven times in a row, how long does it take her to complete them all?

Answer 1

Answer:

  4 minutes 5 seconds

Step-by-step explanation:

Without additional information, we have to assume that one sequence can begin immediately after another, and that each takes the same amount of time. The total time for 7 sequences is 7 times the time for one sequence.

  7 × 35 seconds = 245 seconds = 4 minutes 5 seconds

__

There are 60 seconds in a minute.
