A media student is uploading a promotional video file to a cloud streaming platform.
The student calculates how long it will take to transmit the video file over their network connection.
1 Mbps=10002 bps 1 \text{ Mbps} = 1000^2 \text{ bps} 1 Mbps=10002 bps 1 MB=10242 bytes 1 \text{ MB} = 1024^2 \text{ bytes} 1 MB=10242 bytesThe network upload speed is 40 Mbps.
The video file size is 125 MB.
Construct an expression to show how many seconds it will take to transmit the video file. Show your unit conversions. You do not have to do the final calculation.
