2 and 1/2. Bc 2/5 = 4/10. So 1 hr. = 4/10 2hr. =8/10 and then you need 2 more tons which will only take you half an hour.
R(t) = integral of r'(t) = integral of ti + e^tj + te^tk = 1/2t^2i + e^tj + (te^t - e^t)k + c
r(0) = j - k + c = i + j + k
c = i + 2k
Therefore, r(t) = (1/2t^2 + 1)i + e^tj + (te^t - e^t + 2)k
