solve the proportion using cross products. 20 miles/60 hours=16 miles/h hours?
a.20
b.40
c.48
d.64
??? thanks in advance:) please help!!!
20 miles/60 hours = 16 miles/ h hours
20h mile-hours = 960 mile-hours
divide both sides by mile-hours
20h = 960
divide both sides by 20
h = 48
To solve the proportion using cross products, you need to multiply the two numbers diagonally across from each other. Let's set up the proportion:
20 miles / 60 hours = 16 miles / h hours
Now, cross multiply:
20 miles * h hours = 60 hours * 16 miles
20h = 960
To solve for h, divide both sides of the equation by 20:
h = 960 / 20
Simplifying, we get:
h = 48
Therefore, the answer is c.48
To solve the proportion using cross products, you need to multiply the numerator of one ratio by the denominator of the other ratio and set them equal to each other. Let's solve the given proportion:
20 miles / 60 hours = 16 miles / h hours
Now, cross multiply:
(20 miles) x (h hours) = (16 miles) x (60 hours)
20h = 16 x 60
Simplify the right side:
20h = 960
Now, divide both sides of the equation by 20 to find the value of h:
h = 960 / 20
h = 48
Therefore, the value of h is 48, which corresponds to option c. So, the answer is 48.
