Answer:
[tex]x=12\frac{3}{5}\times 30[/tex]
The rock climber climbs 378 feet in 30 minutes
Step-by-step explanation:
Given,
The rock climber averages 12 and 3/5 feet per minute.
That is, speed of climbing = [tex]12\frac{3}{5}[/tex] ft per min,
Since Distance = speed × time,
If time = 30 minutes,
So, the distance, x, in feet covered by climber,
[tex]x=12\frac{3}{5}\times 30[/tex]
[tex]x=\frac{63}{5}\times 30[/tex]
[tex]x=63\times 6[/tex]
[tex]\implies x = 378[/tex]
Hence, The rock climber climbs 378 feet in 30 minutes
