Question

Mr Cain is adding a home security system that will constantly use 5mbps of his 23mbps plan. How many of his mobile phones can also be used if his blue work phone and laptop must always be on ?

Answer 1

To determine how many mobile phones Mr. Cain can use in addition to his blue work phone and laptop, we need to consider the available bandwidth after accounting for the constant usage of the home security system.

The home security system constantly uses 5 Mbps (megabits per second) out of Mr. Cain's 23 Mbps plan. To find the remaining bandwidth available for other devices, we subtract the constant usage from the total plan speed:

Remaining bandwidth = Total plan speed - Constant usage

Remaining bandwidth = 23 Mbps - 5 Mbps

Remaining bandwidth = 18 Mbps

Now, we need to determine how many mobile phones can be used within this remaining bandwidth. The bandwidth required for each mobile phone depends on the specific activities and applications being used. Let's assume each mobile phone requires an average of 2 Mbps for regular usage.

Number of mobile phones = Remaining bandwidth / Bandwidth per mobile phone

Number of mobile phones = 18 Mbps / 2 Mbps

Number of mobile phones = 9

Therefore, Mr. Cain can use up to 9 additional mobile phones, in addition to his blue work phone and laptop, within the remaining bandwidth of his plan after accounting for the constant usage of the home security system.
