Question

Steve is riding a unicycle.The unicycle tire has circumference of 2.8 meters and revolve 1.5 time per seconds.What is the distance travel in 100 second ?

Answer 1

Answer:

Step-by-step explanation:

The wheel makes 1.5 revolutions per second.

In 100 seconds it will revolve 100 * 1.5 = 15 times (revolutions). Revolutions/sec * sec = revolutions

Each revolution travels 2.8 m.

In 15 revolutions is will travel 2.8 * 15 = 4.2 m.  m/revolution * revolutions = m

 

The trick with "rate" problems usually is to make the units work!

Answer 2

Answer:

The wheel makes 1.5 revolutions per second.

In 100 seconds it will revolve 100 * 1.5 = 15 times (revolutions). Revolutions/sec * sec = revolutions

Each revolution travels 2.8 m.

In 15 revolutions is will travel 2.8 * 15 = 4.2 m. m/revolution * revolutions = m
