Download time depends on file size (in bits, not bytes) divided by connection speed. A common source of confusion: internet speeds are measured in bits per second (Mbps) while file sizes are in bytes (MB, GB). Since 1 byte = 8 bits, a 1 GB file requires 8 Gb (gigabits) of data transfer — so a 100 Mbps connection takes 80 seconds, not 10.
