A car passes by a certain point at t = 0 hours heading east at 40 miles/hour. At t = 1 hour, another car passes by the same point heading north at 50 miles/hour. Which of the following functions equals the distance L (in miles) between the two cars as a function of t, for t is greater than or equal to 1?

a. L = 90t - 50
b. L = square root(4100t)
c. L = square root(4100t^2 + 5000t + 2500)
d. L = square root(4100t^2 - 5000t + 2500)
e. L = square root(90t-50)
