ok first take out the common factor 15 to simplify the problem: 15(t^2 -7t + 12) = 0 now we have to solve the trinomial in the parentheses we need 2 numbers whose product id +12 and whose sum is -7 these are -4 and -3 so it factors to ( t - 4)(t - 3) = 0 ginig t = 3 and t = 4 so your required times are 3 seconds and 4 seconds
so the tshirt will reach the fan at 3 seconds
yea and again at 4 seconds
unless it gets sucked into the fan in 3 seconds!
if so its just as well its a tshirt
