Answer:
27-64
Step-by-step explanation:
cheating in tests are bad, searching for answers in tests is also bad
but the range is 27-64
We know that,![speed = \frac{distance}{time}](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
Julia can finish a 20-mile bike ride in 1.2 hours.
The distance Julia travels is 20 miles and the time she takes is 1.2 hours.
So, Julia's speed =
= 16.67 mph
Katie can finish the same bike ride in 1.6 hours.
The distance Katie travels is 20 miles and the time she takes is 1.6 hours.
So, Katie's speed =
= 12.5 mph
Now, to find how much faster Julia rides than Katie we subtract Katie's speed from Julia's speed.
So, 16.67 mph - 12.5 mph = 4.17 mph = 4.2 mph (approximately)
Thus, Julia rides 4.2 mph faster than Katie.
Answer:
14
Step-by-step explanation:
8x175%= 14
The correct answer would be 3(7+1) because 7+1=8 and 8 times 3 equals 24. 24 divided by six is 4 plus 20 would also be 24.
