# The average speed of a cyclist who covers first, second and third

The average speed of a cyclist who covers first, second and third km at 20, 16 and 12 km/hr respectively (in kmph) is:

(a) 16.24

(b) 16

(c) 15.66

(d) 15.32

**Answer: (d) 15.32 **

**Solution:-**

Total distance covered = 3 km

Total time taken = (1/20 + 1/16 + 1/12) = 47/240

Therefore Average speed = 3/(47/240) km/hr

=15.32 km/hr

Hence, the correct answer is option (d) 15.32.
