Suppose the Mars rover is traveling along a path. At different spots along the path, it collects data about how fast dust is accumulating on it. The table below gives this information: is the distance the rover has traveled and is the rate that the dust is accumulating in mg per km.

Write a right-hand Riemann sum using sigma notation to show the amount of dust that accumulates over the 100 km path given the rates below.

p, the position along path (km) | R(p), the amount of dust per distance traveled (mg/km) |
