Three months ago, Santos could walk 2 miles in 40 minutes. Today he can walk 2 miles in 25 minutes. Find the percent of change and round to the nearest whole percent.

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%
