To find the hiker's ascent rate in kilometers per hour (kph), we need to divide the distance ascended by the time taken.
The hiker ascended 3/4 of a kilometer in 1/16 of an hour.
To divide fractions, we multiply the numerator of the first fraction by the reciprocal of the second fraction.
(3/4) / (1/16) = (3/4) * (16/1) = (3*16) / (4*1) = 48 / 4 = 12
The hiker's ascent rate is 12 kilometers per hour (kph). Therefore, the correct answer is:
12 kph
