Question

suppose that a butterfly can fly 82 feet in 4 seconds. a dragonfly can fly 50 feet in 2 second. which can fly faster and by how much?

Answer 1

the average speed of butterfly is 20.5 ft/s

`(82)/(4) = 20.5`

the average speed of dragonfly is 25ft/s

`(50)/(2) = 25`

so the difference is

`25 - 20.5 = 4.5`
the dragonfly can fly faster 4.5 ft more in a second.

good luck

Answer 2

The dragonfly can fly faster by 4.5 feet per second

The butterfly's speed is 20.5 feet per second
The dragonfly's speed is 25 feet per second
