Question

Крот Борис объявил, что умеет бегать со скоростью 40 м/мин. Ему не поверили, и правильно: на самом деле Борис всё перепутал и думал, что в метре 60 сантиметров, а в минуте 100 секунд. С какой скоростью (в м/мин) бегает крот Борис?   (Стоимость вопроса 24 балла, решать по действиям)

Answer 1

Calculating the Speed of Boris the Mole

To calculate the speed at which Boris the mole runs, we need to convert the given measurements into the correct units. Boris mistakenly believed that there are 60 centimeters in a meter and 100 seconds in a minute. However, the correct conversion is that there are 100 centimeters in a meter and 60 seconds in a minute.

Let's calculate Boris's actual running speed:

1. Convert 40 meters per minute to centimeters per second: - Since there are 100 centimeters in a meter, we multiply 40 by 100 to convert meters to centimeters: 40 * 100 = 4000 centimeters. - Since there are 60 seconds in a minute, we divide 4000 by 60 to convert minutes to seconds: 4000 / 60 ≈ 66.67 centimeters per second.

Therefore, Boris the mole actually runs at a speed of approximately 66.67 centimeters per second.
