Answers

It would be 13 becsue 12.5 time 2 = 25 so round that it = 13
From 40 minutes to 25 minutes is a 62% Change.
First change 40 to 40%. Next change 25 to 30%, then do 40%-30%. Finally that should equal 10%, so it should be around 10%. I don’t know if this is completely right but hopefully it is.

Step-by-step explanation:

decreased minutes = 40 -25 = 15  minutes

Percentage = 15/40 *100 = 1500/40 = 150/4 = 75/2 = 37.5%

Percent of increase in the speed will be 60%.

Step-by-step explanation:

Three months ago speed of walking = \frac{2}{40}

                                                             = 0.05 miles per minute

Walking speed of Santos today = \frac{2}{25}

                                                    = 0.08 miles per minute

Change in speed = 0.08 - 0.05

                             = 0.03 miles per minute

Percent of change in the speed = \frac{0.03}{0.05}\times 100

                                                 = 60%

Therefore, percent of increase in the speed will be 60%

Percent of increase in the speed will be 60%.

Step-by-step explanation:

Three months ago speed of walking = \frac{2}{40}

                                                             = 0.05 miles per minute

Walking speed of Santos today = \frac{2}{25}

                                                    = 0.08 miles per minute

Change in speed = 0.08 - 0.05

                             = 0.03 miles per minute

Percent of change in the speed = \frac{0.03}{0.05}\times 100

                                                 = 60%

Therefore, percent of increase in the speed will be 60%

Let p = percent decrease

(40 - 25)/25 = p/100

Solve for p.

37.5%

Step-by-step explanation:

first work out the difference between the two numbers,

then divide the decrease by the OG number (40)

and multiply the answer by 100

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

2 miles in 40 min = 20 miles per minute
2 miles in 25 minutes = 12.5 miles per minute

(20 - 12.5) / 20 = 7.5/20 = 0.375 = 37.5% change
