Tom and jack “power walk” towards each other at the same time. tom’s walking speed is 2.3 m/s, jack’s speed is 2.2 m/s. they meet each other 1.5 minutes after they started. how far apart were they to begin with?

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.
