Answer:
325 and 375 mph
Step-by-step explanation:
Given :
Distance between plane A and B = 2800
Recall :
Distance = speed * time
Let speed of A = v1
Speed of B = v2
v1 = v2 + 50
Time taken = 4 hours
Distance = speed * time
Total distance = 2800
2800 = v1 * 4 + v2 * 4
2800 = (4v1) + (4v2)
2800 = 4(v2+50) + 4v2
2800 = 4v2 + 200 + 4v2
2800 = 8v2 + 200
2800 - 200 = 8v2
2600 = 8v2
v2 = 2600/8
v2 = 325 mph
v1 = v2 + 50
v1 = 325 + 50
v1 = 375 mph
Answer:
30 + 0.89m
Step-by-step explanation:
I think this is the correct answer.
45 multiply 1/2 and 90 put it in the calculator 90 times 0.5
Answer:
x=
1/2
Step-by-step explanation:
6x+9=12
Step 1: Subtract 9 from both sides.
6x+9−9=12−9
6x=3
Step 2: Divide both sides by 6.
6x/6=
3
/6
And Your Answer Will Be:
x=
1/2
