Homework Statement
A cheetah, the fastest of all land animals over a short distance, can accelerate from zero to 18.0 m/s in three strides and to a full speed of 31.3 m/s in seconds. Assuming the first three strides are each 4.1 m long and that acceleration is constant until the cheetah reaches full speed, what is the cheetah's acceleration (in m/s2)?

The Attempt at a Solution
It is a basic question, but I am over looking something because I cannot figure out which equation I should use. From what I know, I need time to find out what the acceleration is, but no time variable is stated. The question also gives you the stride lengths which just confuses me even more.
