Speed up your Capybara JS specs you can turn off jquery animation. In this case all animations will immediately set elements to their final state when called, rather than displaying an effect.

# Problem 1 of 3: Math
# ====================
#
# n! means n * (n - 1) * ... * 3 * 2 * 1
# For example, 10! = 10 * 9 * ... * 3 * 2 * 1 = 3628800
# Let R(n) equal the sum of the digits in the number n!
# For example, R(10) is 3 + 6 + 2 + 8 + 8 + 0 + 0 = 27.
# Find the lowest value for n where R(n) is 8001.
#
# Result: 787.
