I hope you see the pattern here . When multiplying the exponent (the small number near the 10) determines the number of zeros to the RIGHT . When dividing the number determines how many zeros to the LEFT usually resulting in a decimal. This is called scientific notation.
Hope this helps!:)
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 are all the factors of 60. If a list includes any number other than what is listed here, it is NOT a choice.
We need to know the distance
Distance = speed × time
Speed = 60 - 10 = 50 mph
Time = 1 hr
Therefore Distance = 50 × 1 = 50 miles
X - y = 2400/6 = 400 where x = speed of plane and y = speed of wind.
x + y = 2400/5 = 480 - flying with the wind
adding the 2 equations
2x = 880
x = 440
Speed of the plane with no wind = 440 mph
