The circumference of a bicycle wheel is 1.4 / 5m. In 1 second, the wheel makes 1.2 / 3

The circumference of a bicycle wheel is 1.4 / 5m. In 1 second, the wheel makes 1.2 / 3 revolutions. What S will the bicycle pass in 5 minutes.

For the convenience of the calculation, we convert the values of the wheel circumference, as well as the number of revolutions per second, to the form of an irregular fraction:

1 4/5 m = 9/5 m

1 2/3 rpm = 5/3 rpm

Let us determine which path the wheel travels in one second – for this we calculate 5/3 of the wheel’s circumference:

9/5 * 5/3 = 9/3 = 3 m the bike travels in a second.

Now let’s convert the time into seconds:

5 * 60 = 300 s

Let’s determine the distance that the bike will travel in 5 minutes:

3 * 300 = 900 m.

Answer: in 5 minutes the bike will travel 900 m.
