What is 7.8×105 hours in days?
A)1.872×10^4 days
B)3.250×10^6 days
C)1.872×10^8 days
D)3.250×10^4 days
Explanation:
D) 3.250×10^4 days
You know there are 24 hours in a day, so the number of hours must be divided by the hours per day to find the number of days:
(7.8×10⁵ h)/(2.4×10¹ h/da) = (7.8/2.4)×10⁵⁻¹ da = 3.250×10⁴ da
