Step-by-step explanation:
Can you show all the answer choices, so I know if I am correct or not?
Step One
========
Start with how much was transferred.
r = 4.4 megabytes / second
t = 32 seconds
amount transferred = ????
Formula: amount = r*t
amount = 4.4 * 32 = 140.8 megabytes were transferred.
Step Two
=======
Find the number of megabytes on the drive before the transfer took place.
The amount transferred = 140 megabytes.
The drive recorded when he was done there was 384 megabytes
The amount on the drive was 384 - 140 = 243.2 megabytes to begin with.
Step 3
=====
Find the number of megabytes left before the transfer.
1000 - 243.2 = 756.8 megabytes were left before he began his 32 second transfer.
Step 4
=====
Find the amount of time it would take to fill the drive.
He needs to transfer 756.8
The rate of transfer = 4.4 megabytes / second
t = ????
Formula: Amount transferred = r * t; t= amount / r
t = 756.8 / 4.4
t = 172 seconds.
Interesting question. Thanks for posting. It is a unique application of the more familiar formula
d = v * t
IT'S FALSE!! All the sides of a scalene triangle are UNEQUAL. YOU'RE WELCOME :D
