Sagot :
2 miles out of 40 minutes or 2/40 is .05
2 miles out of 25 minutes or 2/25 is .08
so he increased by .03 miles per minute
Answer:
Percent of increase in the speed will be 60%.
Step-by-step explanation:
Three months ago speed of walking = [tex]\frac{2}{40}[/tex]
= 0.05 miles per minute
Walking speed of Santos today = [tex]\frac{2}{25}[/tex]
= 0.08 miles per minute
Change in speed = 0.08 - 0.05
= 0.03 miles per minute
Percent of change in the speed = [tex]\frac{0.03}{0.05}\times 100[/tex]
= 60%
Therefore, percent of increase in the speed will be 60%
