The distance 4(in miles) that a car travel on highway in x minutes is represented by the equation y=1.1x. The graph shows distance that a bus travles[(2,2.1) (4,4.2)]. Find the speed of each vehicle. Which vehicle is travelling faster?

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
