Please answer the following question.

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)


0 6


20 3.5


40 2.5


60 2


80 1.5


100 1
