Use scientific notation to solve the problem.
-A computer can do one calculation in $1.4 \times 10 ^ { - 7 }$ seconds. How long would it take the computer to do a trillion (1012) calculations?
A) $1.4 \times 106 \mathrm { sec }$
B) $1.4 \times 10 ^ { 12 } \mathrm { sec }$
C) $1.4 \times 10 ^ { 5 } \mathrm { sec }$
D) $1.4 \times 10 ^ { - 7 } \mathrm { sec }$

Question

Quizplus · Accepted Answer

To find the total time, multiply the time per calculation by the number of calculations: $1.4 \times 10^{-7} \times 10^{12} = 1.4 \times 10^{5}$ seconds.
