Write and solve the inequalitiy

Answer 1

We know that
Peter has already delivered  2 pizzas in 5 minutes
so
1 hour-------> 60 minutes
time left------> 60 minutes - 5 minutes--------> 55 minutes 

pizzas to deliver to beat his previous record----------> 20-2------> 18 pizzas

therefore
in the next 55 minutes

if the

average per minute = (18/55) pizzas /minute
Pete beat his previous record

 average per minute  > (18/55) pizzas /minute
Pete overcome the previous record

 average per minute  < (18/55) pizzas /minute
Pete will not match the previous record
