A snail crawls a clearing in 30 hours and 20 minutes, and a cheetah runs this distance in 16 seconds. What is the average speed of a snail if the average speed of a cheetah is 100 km / h.
These tasks: t1 (time of movement of the snail in the clearing) = 30 h 20 min (30 1/3 h); t2 (the duration of the run of the cheetah) = 16 s (0.00444 h); V2 (average speed of a cheetah) = 100 km / h.
The average speed of the snail can be expressed from the equality: V1 * t1 = L (length of the clearing) = V2 * t2, whence V1 = V2 * t2 / t1.
Calculation: V1 = 100 * 0.00444 / (30 1/3) = 0.01465 km / h = 14.65 m / h.
Answer: The speed of the snail is 14.65 m / h.
