Question

If I spoke with 800 customers in 40 hours how many customers did I speak to every 30 minutes

Answer 1

10 customers were spoken to in every 30 minutes

Explanation:

First, we convert 40 hours into minutes by multiplying it with 60 [as 1 hour = 60 minutes]

So, 40 hours = 40*60 minutes

= 2400 minutes

In 2400 minutes, number of customers served = 800

In 1 minute, number of customers served =
`(800)/(2400)`

In 30 minutes, number of customers served =
`(800)/(2400)*30`

=
`(800)/(2400) * (30)/(1)`

=
`(800*30)/(2400*1)`

=
`(24000)/(2400)`

= 10

So,

10 customers were spoken to in every 30 minutes
