Mr. ben drove from town a to town b. for the first 3 hours, he traveled at an average speed of 60 km/h, and after that, he drove at another average speed of 70 km/h. if the distance between town a and b is 460 km, what was the total time for the whole journey?

7 hours

Step-by-step explanation: For the first 3 hours he traveled at an average speed of 60km. So we would multiply 60 by 3 and get 180. Then we would subtract 180km from 460km. And we would get 280km. Now we would divide 280 by 70km to get 4. Now we add 4 hours and 3 hours to get 7 hours. Answer : 7 hours

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
