Question

A scooter travels 30 feet in 2 seconds at a constant speed. A skateboard travels 55 feet in 4 seconds. Is the skateboard going faster, slower or the same speed as the scooter?

Answer 1

Let's first compute the speed of the scooter and the skateboard. Once we have their respective speed rate, the higher the speed means faster it is.

Let's compute the speed by this formula:

`\text{ Speed = }\frac{D\text{istance}}{Time}`

A. Let's determine the speed of the scooter traveling 30 ft. in 2 seconds.

`\text{ Speed = }\frac{D\text{istance}}{Time}\text{ }\rightarrow\text{ Speed = }\frac{30\text{ ft.}}{2\text{ seconds}}`
`\text{ Speed = }15\text{ ft./seconds}`

B. Let's determine the speed of the skateboard traveling 55 ft. in 4 seconds.

`\text{ Speed = }\frac{D\text{istance}}{Time}\text{ }\rightarrow\text{ Speed = }\frac{55\text{ ft.}}{4\text{ seconds}}`
`\text{ Speed = 13.75 ft./seconds}`

The scooter's speed is 15 ft./seconds while
