19)A computer can execute 64 instructions per microsecond. How many instructions can it execute in 10 minutes?
A microsecond isOne millionth (10 -6) of a second

Answer
1 minute = 1X60 X10^6 microseconds

10 minute = 10 X 60 X 10^6 microseconds

10 minutes = 6.0 X 10^8 microseconds

in 1 microseconds computer execute 64 instruction

so in 6 X 10^8 it will execute = 64 X 6X 10^8 = 384 X 10^8 instructions
