A hiker ascended 3/4 of a kilometer in 1/16 of an hour. What was the mountain hiker's ascent rate in kilometers per hour (kph)?
(1 point)
A. 12 kph
B. 3 kph
C. 16 kph
D. 9 kph
To find the ascent rate in kilometers per hour (kph), we need to divide the distance ascended by the time taken.
Distance ascended = 3/4 kilometer
Time taken = 1/16 hour
Ascent rate = Distance ascended / Time taken
Ascent rate = (3/4 kilometer) / (1/16 hour)
To divide by a fraction, we can multiply by its reciprocal.
Ascent rate = (3/4 kilometer) * (16/1 hour)
Ascent rate = 48/4 kph
Ascent rate = 12 kph
Therefore, the mountain hiker's ascent rate was 12 kph. Answer: A. 12 kph.
