A hiker ascended of 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
• 12 kph
• 3 kph
• 16 kph
• 9 kph
To find the ascent rate, we need to divide the distance climbed by the time taken. The hiker ascended 3/4 of a kilometer in 1/16 of an hour, so the ascent rate is (3/4) / (1/16).
To divide by a fraction, we multiply by its reciprocal. In this case, we need to multiply by 16/1.
So, (3/4) / (1/16) = (3/4) * (16/1) = 48/4 = 12 kilometers per hour (kph).
Therefore, the mountain hiker's ascent rate is 12 kph.
