Question

Given the speeds of each runner below, determine who runs the fastest. \text{Brooke runs 13 feet per second.} Brooke runs 13 feet per second. \text{Will runs 308 feet in 26 seconds.} Will runs 308 feet in 26 seconds. \text{Ron runs 1 mile in 551 seconds.} Ron runs 1 mile in 551 seconds. \text{Debbie runs 658 feet in 1 minute.} Debbie runs 658 feet in 1 minute.

Answer 1

Brooke runs the fastest.

Explanation:

Brooke runs 13 feet per second.

Therefore, speed of Broke = 13 feet per sec.

Will runs 308 feet in 26 seconds.

Speed of Will =
`\frac{\text{Distance}}{\text{Time taken}}`

=
`(308)/(26)`

= 11.85 feet per second

Ron runs 1 mile in 551 seconds.

1 mile = 5280 feet

Speed of Ron =
`(5280)/(551)`

= 9.58 feet per second

Debbie runs 658 feet in 1 minute.

1 minute = 60 seconds

Speed of Debbie =
`(658)/(60)`

= 10.97 feet per seconds

Here, speed of Brooke is the maximum.

Therefore, Brooke runs the fastest.
