Answer:
x - 1.7 = 14
Step-by-step explanation:
Sarah thought of a number: x
Then she subtracted 1.7 FROM it: x - 1.7
and gets an answer if 14: x - 1.7 = 14
so the equation is x - 1.7 = 14
We need explaining and examples not just the question
11 miles in 1/4 hour
1/4 of an hour is 15 minutes
so 11 in 15 minutes
x /60 = 11/15
cross multiply
x*15 = 60 * 11
15x = 660
divide both sides by 15
x = 44
the unit rate of the hikers in miles per hour is 44 mph.
You can also solve like this
1/4 of hour is 15 minutes
to get to the whole hour you would multiply by four
so you'd (11miles in 1/4 hour) * 4
44 miles in 1 hour
Hope this helps :)
