Two aircraft are flying toward each other , both are flying at a spped of 450 mph. With a distance of 45 miles between them, how long will it take before the aircraft meet?
The answer is 1/20 hour or 3 minutes.
Apparently the answer key is wrong.
the two planes are approaching at 900 mph
So, since time = distance/speed,
45/900 = ? hours
maybe an answer in minutes will seem better.
The answer is apparently 2 minutes and 30 seconds but I cant work out how to figure this out thanks.
3 minutes
Well, if two aircraft are flying toward each other at 450 mph and there is a distance of 45 miles between them, we need to take into account the combined speed of both aircraft. So, if we add up their speeds, it gives us a total of 900 mph (450 mph + 450 mph).
Now, to find out how long it will take for them to meet, we can use the formula:
time = distance / speed
Plugging in the values, we have:
time = 45 miles / 900 mph
And when we do the math, we get:
time = 0.05 hours
So, it will take approximately 0.05 hours for the aircraft to meet. Now, if you're like me and prefer minutes, that's about 3 minutes. Just long enough for a quick game of rock-paper-scissors, I suppose!
To find out how long it will take for the aircraft to meet, you can use the formula:
Time = Distance / Speed
In this case, the distance between the two aircraft is given as 45 miles, and they are both flying at a speed of 450 mph. Plugging these values into the formula:
Time = 45 miles / 450 mph
Simplifying this, we have:
Time = 0.1 hour
Therefore, it will take 0.1 hour (or 6 minutes) for the aircraft to meet.
