A hiker ascended 3/4 of a kilometer in 1/16 of an hour. What was the hiker's ascent rate in kilometers per hour? A. 12 kph B. 3 kph C. 16 kph D. 9 kph
To find the ascent rate in kilometers per hour, we need to divide the distance ascended (3/4 km) by the time taken (1/16 hour).
Distance/time = ascent rate
(3/4 km) / (1/16 hour) = (3/4) * (16/1) km/hour = 12 km/hour
Therefore, the hiker's ascent rate was 12 kilometers per hour. The correct answer is A. 12 kph.
