The rate of the jet stream is 100 miles per hour. Traveling with the jet stream, an airplane can fly 1200 miles in the same amo
1 answer:
Answer:
x = 600 mph
Step-by-step explanation:
It is given that,
Speed of the jet stream = 100 mph
It travels 1200 miles in the same amount of time as it takes to fly 1000 miles against the jet stream.
We need to find the airplane's average rate in calm air. Let it is equal to x mph.
As time in same in both cases. ATQ,
So, the airplane's average rate in calm air is 600 mph. Hence, this is the required solution.

This is fairly simple. Divide 2,871,000 by 10 and that's your answer!
Also, since you're dividing by a factor of 10 (or in this case, <em>10</em>) you can just take away as many places as are zeros in the number you're dividing from. This works for <em>10, 100, 1,000, 10,000, etc. </em>In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.
