Question

16. How long will it take for a bowling ball to travel a distance of 40 meters if it is moving at aspeed of 10 m/s?

Answer 1

A speed of 10 m/s means that it takes 1 second for the ball to travel 10 meters. To find how long will it take to travel 40 meters, we can use the next proportion:

`\frac{10\text{ meters}}{40\text{ meters}}=\frac{1\text{ second}}{x\text{ seconds}}`

Solving for x:

`\begin{gathered} 10\cdot x=1\cdot40 \\ x=(40)/(10) \\ x=4\text{ seconds} \end{gathered}`

It will take 4 seconds to travel 40 meters
