Answer:
y = 460 miles per hr
x = 500 miles per hr
Step-by-step explanation:
Let the planes be X any
Let their speeds be xmiles/hr and ymiles/hr respectively
x = y + 40 (assuming X is faster by 40miles/hr)
Distance travelled by X to meet Y = 0.75x
Distance travelled by Y to meet X = 0.75y
0.75x + 0.75y = 720 --------1
Put x = y + 40 in eqn 1
0.75(y+40) + 0.75y = 720
0.75y + 30 + 0.75y= 720
1.5y = 690
y = 460 miles per hr
x = 460 +40
= 500 miles per hr
Answer:
4 pounds
Step-by-step explanation:
1/3 x 3 = 1
1/12 x 3 = 3/12 = 1/4
to get one whole, multiply by 4
1/4 x 4 = 1
1 x 4 = 4
Answer:
37923004188
Step-by-step explanation:
Speed = distance / time
speed = 1(mile) / 4 (minutes)
speed = 0.25 miles per minute
s = 0.25m <== ur equation
there are 60 minutes in an hr....so sub in 60 for m
s = 0.25(60)
s = 15 miles per hr <====
