Answer:
Velocity of jet in still air is 800mph hour and velocity of wind is 180mph
Step-by-step explanation:
Let the velocity of jet in still air be x miles per hour and velocity of wind be y miles per hour.
#Jet's velocity against jet-stream is:
#Jet's velocity with jet-stream:
#The velocity against jet-stream is x-y and with jet-stream is x+y:
Hence,velocity of jet in still air is 800 mph hour and velocity of wind is 180 mph.
Answer:
10
Step-by-step explanation:
Means back the numbers into multiples of several small numbers
Like:; 1. We take LCM of 40
Just break into multiples of small number
40= 2×2×2×5
2. We take LCM of 50
50= 5×5×2
So LCM for 100 is 2×2×5×5
after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)
Then write the the single number in place of two multipled numbers
Like:; 2×2 is written as 2 // 3×3 is written as 3
So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)
write pairs in single number 2×5
And so we get 2×5=10
So we find root of 100 that is 10
