Question

Urgent please help I am so lost thank you a lot

Answer 1

• Answer: X = 130 mph

Therefore, The Speed of the plane is: X = 130 mph

• Explanation:

520 / x = 160 / x - 90

• Rearranged the variables:

520/x = 160/x - 90

• Undefined Variables:

x ≠ 90

x ≠ 0 and x - 90 ≠ 0

• Cross Multiply:

520x - 46800 = x * 160

• Now We Solve the problem:

520/x = 160/x - 90

520(x - 90) = 160x

520x - 46800 = 160x

520x - 160x = 46800

360x = 46800

x = 46800/360

x = 130

• Draw the conclusion:

Therefore, The Speed of the plane is: X = 130 mph

I hope this helps you!
