What was his average speed?I was guessing he traveled 350 miles in 6 hours so would his average speed be 58.3 mph?-Yep, sounds good - average speed = total distance / total time-First, add up how many total miles jack drove.......
Not really looking for an answer but what steps do i take to solve this:

On a vacation trip, Jack left at 10am and traveled 100 miles, then he took a 30 minute break. He then traveled another 140 miles and stopped for another 30 minute break. Finally, he traveled 110 miles and arrived at his destination at 4 pm. What was his average speed?

I was guessing he traveled 350 miles in 6 hours so would his average speed be 58.3 mph?

First, add up how many total miles jack drove.
140+100+110=350 miles
Then add up how many total hours he drove
6hours - 1 hour(two 30 min breaks) = 5 hours
Then divide the total miles by the total hours
350/5 = 70 mph

I think this is right. If not SORRY. GOOD LUCK!!

Basically he traveled 350 miles in 5 hours. (1 hour in breaks taken off). His average speed was 70 miles per hour.

He wasn't moving during his breaks so don't count the two 30 minute breaks.

-
410 miles in 6 hours and 68.3 in speed

-
yes it;s correct, but if you want to have average speed of car U must calculate 350/5, because he was resting for 1 hr.

-
Correct

-
350/5 because you have to account for the hour he wasn't traveling
70 mph
question is a little vague

-
I hate math

-
Its right
