Your family leaves home at 9 am. At that point, the cars odometer reads 31,247 miles. You drive until 12:30 pm when you and your family stop for lunch. At the restaurant, the odometer reads 31,492 miles. What is the unit rate in speed for miles per hour

answer: #1 ads up by 8 and i don't know #2

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
