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

Answer:10 customers were spoken to in every 30 minutesStep-by-step 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 minutesIn 2400 minutes, number of customers served = 800In 1 minute, number of customers served = [tex]\frac{800}{2400}[/tex]In 30 minutes, number of customers served = [tex]\frac{800}{2400}*30[/tex]                                                                          = [tex]\frac{800}{2400} * \frac{30}{1}[/tex]                                                                          = [tex]\frac{800*30}{2400*1}[/tex]                                                                          = [tex]\frac{24000}{2400}[/tex]                                                                          = 10So,10 customers were spoken to in every 30 minutes
