Answer: 7.5 miles per hour
Step-by-step explanation:
First speed was 3 miles per hour.
Second speed was 12 miles per hour.
To do an average, add both speeds and divide by two, which is the number of trips made.
= (3 + 12) / 2
= 15 / 2
= 7.5 miles per hour

tell me the answer please
Largest 5-digit number is 54312 and is divisible by 6. The smallest 5 digit number is 12,345 and it's not divisible by 6
Add the temps up
-24 + (-15) + (-21) + (-32) + (-18) + (-9) + (-14) = -133
now divide by how many numbers there are
-133/7 = -19 <== the mean (average)
