miles
[2]
8

264 miles

Step-by-step explanation:

Let's convert 3 hours and 40 minutes into hours first.

Recall that 1 hour = 60 minutes.

Therefore 40 minutes = 40/60 hours = 2/3 hours.

The car travelled 3 and 2/3 hours in total.

Recall that distance = speed times time.

The car has travelled 72 x 3 2/3 miles = 264 miles.

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%
