At t = 0 seconds, a truck is traveling east at a constant speed of s = 85.3 km/h. At an intersection d = 33.7 km ahead, a car is traveling north at a constant speed of v = 40.5 km/h. Write an expression for the distance, r, between the truck and the car as a function of time. Use the variables from the problem statement for your equation.
A) r = √((85.3t)² + (33.7 - 40.5t)²)
B) r = √((85.3t)² + (40.5t - 33.7)²)
C) r = √((85.3t - 33.7)² + (40.5t)²)
D) r = √((85.3t + 33.7)² + (40.5t)²)
