Answer:
Option B
Step-by-step explanation:
Speed is distance moved per unit tine and is expressed as s=d/t
Making d the subject then
d=st
Where d is distance, s is speed and t is time taken in time.
Conversion
1 hour has 60 minutes hence 45 mins converted to hours will be 45/60=0.75
Substituting 0.75 hours for t and 170 mph for s then
d=0.75*170=127.5 miles due North
However, tge plane had initially moved 12.5 miles hence the relative distance due North will be 127.5-12.5=115 miles due North
437 is the answer that i got
Answer:
221 minutes
Step-by-step explanation:
His goal is 8 minutes or less for every mile during the marathon.
8 x 52 = 416
That gives him 416 total minutes to complete the marathon goal.
He already ran the first half in 195 minutes, so we do this to find the time for the other half:
416 - 195 = 221
He has 221 minutes in the second half of the marathon to meet his goal.
A and B lie on the line, yes, but what specifically are you supposed to do? Looks like your problem statement was cut off before you'd finished typing it in.
You say your line passes thru (-2,5) and has a slope of 2/3? Then, using the point-slope formula,
y-5 = (2/3)(x+2) This is the general equation for your line.
Now let's play around with B(-2,y). Suppose we subst. the x-coordinate of B, which is -2, into the equation y-5 = (2/3)(x+2); we get y-5 = (2/3)(-2+2) = 0. This tells us that y must be 5. But we already knew that!!
So, please review the original problems with its instructions and this discussion and tell me what you need to know from this point on.
