We know that <span>Peter has already delivered </span><span> 2 pizzas in 5 minutes so 1 hour-------> 60 minutes </span><span>time left------> 60 minutes - 5 minutes--------> 55 minutes
</span>pizzas to deliver to beat his previous record----------> 20-2------> 18 pizzas
therefore in the next 55 minutes
if the
<span>average per minute = (18/55) pizzas /minute </span>Pete beat his previous record <span> </span>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
What you need to do is do the formula of Area=1/2×Height (Base B +Base A) Base B is bottom Base A is the top then you divide by 2 In this case 1/2 ×8/1 ×(12+15)=108
