anonymous · Answer

strange way to ask:
"solve $|1.5-53t|=0.1$ for $t$

anonymous · Answer

how do u slove?

anonymous · Answer

|1.5−53t| = 0.1

implies

1.5 - 53t = 0.1 and 53t - 1.5 = 0.1

anonymous · Answer

answer?

anonymous · Answer

you just solve for t in each equation to get each answer.  your values of t will be in hours, so you have to convert them into seconds

anonymous · Answer

i'll do the first one for you

1.5 - 53t = 0.1
1.5 = 0.1 + 53t
1.4 = 53t
0.026415 = t
0.026415 * 60 min/h * 60 s/min = 95.094 seconds or about 95.1 seconds
