Answer:
26 2/3 mph
Step-by-step explanation:
time = distance/speed
speed = distance/time
Use the first of these relations to find Aidan's time getting to school:
time = 16 mi/(40 mi/h) = 16/40 h = 0.4 h
Then the time Aidan takes to get home is 0.6 hours, and his average speed for that trip home is ...
speed = 16 mi/(0.6 h) = 26 2/3 mi/h
Answer:
b/(b+a)
Step-by-step explanation:
(1/a)-(1/b) :[ (b²-a²)/ab²]
first solve :
common denominator ab
(1/a)-(1/b) = (b-a)/ab
[b-a/ab] : [(b²-a²)/ab²]
when divide fraction ( division sign turn to (×) and flip the second fraction(reciprocal):
[b-a/ab] × [ab²/ (b²-a²)]
then simplify : ab²/ab = b
(b-a)×(b/b²-a²)
factorize : b²-a² = (b-a)(b+a)
(b-a)×(b/(b-a)(b+a)) simplify : (b-a)/b-a = 1
[(b-a)(b)]/[(b-a)(b+a)
b/b+a
12 x 12 x 12
explanation: 12 to the 3rd power is simply just 12 times itself 3 times.
