Jacqueline has hiked 125 feet and hikes 1.2 feet per second. Rick has hiked 10 feet and hikes 2.6 feet per second. After how many seconds will Jacqueline have hiked no less than the number of feet Rick has hiked?

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.
