Answer:

28%

Step-by-step explanation:

Lets say the fraction of speed and problem solved is 100/100

the number of problems solved increases by 60%

so now it is 160/100, also the speed increases by 25%

so now we do 160/125=1.28

finally we do 1.28-1 = 28%

Therefore the answer is 28%.

hope this helps

The number of mathletes on the team must increase by 28%.

The speed of the mathletes is total number of questions divided the total number of people on the team.

Speed = total number of questions / total number of people on the team

Increase in the number of people on the team = total number of questions / speed

1.60 / 1.25 - 1 = 28%
