Question

Jamel travels 450 feet in 10 seconds on his bicycle. At this rate, how many feet can he travel in one minute?How many feet can Jamal travel in 1 second?Use the unit rate to help you answer the 1st question.

Answer 1

We know that Jamel travels 450 feet in 10 seconds.

We can calculate the unit rate (in this case, the speed) by dividing the distance by the time:

`v=\frac{450\text{ ft}}{10\text{ s}}=45\text{ ft/s}`

Then, we can use this rate to calculate how many feet he can travel in one minute.

As 1 minute = 60 seconds, we can write:

`\begin{gathered} d=v\cdot t \\ d=45(ft)/(s)\cdot(1\min \cdot(60s)/(1\min))=45\cdot60ft=2700ft \end{gathered}`

As the unit rate already tells us the distance he can travel per second (45 ft/s), we can conclude that in one second he will travel 45 ft.

Answer: In one minute, he can travel 2700 ft.

In one second, he can travel 45 ft.
