A half game in football is 45 min. At one point, a half was extended so that it was 48 minutes 30 seconds long. By what percenta
kozerog [31]

Answer:

8%

Step-by-step explanation:

Multiply the number 45 by at least 1 point 0 something and therefore.  We can assume that a 5% increase is around 47 minutes and 15 seconds and a 10% increase is around 49 minutes and 30 seconds ranging for you to use from 6% to 9%.  The exact answer for the increase is around 7.78%, for me, I would plug in the equation like 45*1.7 and 45*1.8 on the calculator for more accuracy since you would need to round to the full percentage if it's between 7.5% to the exact number, it would be fully rounded to 8% since you would need at least a 5 to round up.
