Answer:24
Step-by-step explanation:
Since the numbers in the middle are 21 and 27, you add both and divide by 2 to get the number in the middle of those 2.
117miles/180minutes ~~ 117miles/3hours ~~ miles/hour(mph)
117miles ÷ 3hours = 39miles/hour or 39 miles per hour.
(<em>Speed=x</em>) Speed needed is: x ≥ 39mph.

Answer:
There is 7/15 left in the bag
Step-by-step explanation:
So, you need to find a common denominator between 3 and 5 which is 15
multiply the numerator and the denominator by 3 in 1/5. Then, multiply the numerator and the denominator by 5 in 1/3.
1/3*5=5/15
1/5*3=3/15
Add them together.
5/15+3/15=8/15
Lastly, subtract 15/15 by 8/15
15/15-8/15=7/15
