Evan’s family drove to a theme park for vacation. They drove the same speed throughout the trip. The first day, they drove 300 m
Ray Of Light [21]
Answer: Evan's family drove 150 miles on the third day.

Explanation:
Because they had driven the same speed throughout the trip, dividing the miles driven by the hours would result in the miles that they drove per hour. 300/6 and 250/5 = 50. So, Evan's family drove 50 miles per hour. To solve for the hours driven on the third day, you need to multiply the hours driven by the miles that were driven per hour. 

3 hrs. x mph (miles per hour) = miles driven on the third day

Hope this helps! Sorry, I don't have the time to reread my answer, but I'm positive that it'll make sense to you somewhat.

The pitcher for the Robins throws a baseball at 90.0 miles per hour. The pitcher on the Bluebirds throws a baseball 112.2 feet p
Margaret [11]
The pitcher for the Robin's throws faster. You know this because you can multiply 112.2 by 60 seconds to equal one minute. You want to get equal minutes, so multiply the answer of 112.2 x 60(6,732) by 60 once again to equal one hour, or sixty minutes. The answer you get(403,920), you divide by 5280 since there are 5280 feet in one mile. You should see that the Bluebird's pitcher throws 76.5 mph which s slower than the Robin's.
