Which rate can you set 30/1 equal to in order to find the time it takes to travel 900 miles at 30 miles per hour?

30 hours

Step-by-step explanation:

30/1 = 900/x

Cross multiply

30x = 900

x = 900/30

x= 30 hours

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
