Answer 2

Answer:

So, average speed when traveling downhill = 19.6 meter/hour

Step-by-step explanation:

Average speed of the cyclist on the flat = 14 m/hour

Given that the speed of the cyclist increases if he travels downhill.

Increase in percentage when the cyclist travels downhill = 40%

So, increase in speed = 40% of average speed on the flat

                                     = 40% of 14

                                     = 0.4 × 14

                                     = 5.6 m/hour

So, average speed when traveling downhill = 14 + 5.6

                                                                         = 19.6 meter/hour
