Question

A particular network service provider charges 50 Kobo per second to make a call. How many minutes will a caller with 300 naira airtime last.​

Answer 1

9514 1404 393

Answer:

10 minutes

Explanation:

The current legal tender conversion rate is 50 kobo = 0.50 naira. Then the airtime balance is ...

(300 NGN)/(0.50 NGN/s) × (1 min)/(60 s) = 300/(0.50×60) min = 10 min
