Method of moments for pothole rate

Let $\{N(t)\}_{t\ge0}$ be a Poisson process with rate $\lambda$, where $\lambda > 0$ is an unknown parameter. Starting from the origin, an intercity road has $N(t)$ number of potholes up to a distance of $t$ kilometers. Starting from the origin, potholes are found at the following distances (in kilometers) 0.9,1.3, 1.8,2.7,3.4,4.1,4.7,5.5,6.2,6.8,7.4,8.1,8.9,9.2,9.7. Based on the above data, the method of moment estimate of $\lambda$ equals ________ (rounded off to two decimal places).
