Dina and masha started out on a 12 mi bike path at the same time. when dina reached the end of the 12 mi, masha still had 3 mi left to bike. if dina’s biking speed is 8 mph, find masha’s biking speed.

6 mph

Step-by-step explanation:

Use formula

where

D = distance

r = rate

t = time

In your case,

D = 12 mi

Dina:

D = 12 mi

r = 8 mph

t = ?

So,

Masha:

D = 12 - 3 = 8 mi

r = ?

t = 1.5 hours

Then

do you have the measurements?

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
