Natali [406]

9514 1404 393

Answer:

28%

Step-by-step explanation:

If x represents the fractional increase in the number of mathletes, and if problem-solving speed is jointly proportional to their speed and their number, we want ...

(1 +25%)(1 +x) = (1 +60%)

1 +x = 1.60/1.25 = 1.28

x = 0.28 = 28%

The team size must increase by 28% to solve all of the problems on time.
