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

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
