You can drive 720 miles in 8 hours on 32 gallons ?how far can you drive in 1 hour?

there is a picture

Answers

So if you go 720 miles in 8 hours, you would travel at a speed of:720 miles / 8 hours = 90 miles per hour.So in 1 hour, you would have traveled:90 miles per hour * 1 hour = 90 miles.(The gallons is irrelevant to the problem)
720 in 8 hours
the ratio is 720 to 8 or 720:8
this can be like fraction as 720/8
simplify it since 8=hours and you want 1 hour
720/8=360/4=180/2=90/1

Finds the solutions to x^2=20

Answers

Solution of an equationx^(2) =20 is x= \pm 2√(5).

What is solution of an equation?

The solution of an equation is the array of all values that, when replaced for unknowns, make an equation true.

Given

x^(2) =20

x=√(20)

x=√(4 * 5 )

x=\sqrt{2^(2) * 5}

x= \pm 2√(5)

Solution of an equationx^(2) =20 is x= \pm 2√(5).
