Accepted Solution

A:

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
