So that is equal to 180 miles per 2 hours which is 90 miles per hour if each hour has the same m/hr rate.
You can set up a proportion:
let x = number of miles per hour
cross multiply and you get
2x=180
divide both sides by 2 and you get
x=90
so you get the same answer both ways,
90 miles per hour

Answer:
1.78
Step-by-step explanation:
To solve for x we need to cross multiply it
We have = sign inbetween the fractions so we cross multiply it
9*x = 2* 8
9x = 16
Now we divide by 9 on both sides
so x= 1.7777777778
When we round to two decimal places then
x= 1.78
