An asteroid is 10^{14} miles away from earth, and it is traveling at a speed of 10^{3} miles per day. How many days will it take the comet to reach earth? Answer in a^b form

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition. 

21/2 or 5/2
