Step-by-step explanation:
You can first convert the mixed numbers into fractions and then operate them
if for example you have 3 4/3
to convert it you first multiply the whole by the denominator and then you add the nominator. The denominator is the same.

Answer:
Stacey is 16 miles far from the beginning of the trail.
Step-by-step explanation:
Given:
Stacey's total hike journey to NCT, Colorado = 18 miles
Distance covered by her to, a resting spot = 4 miles
We have to find:
How far from the beginning of the trail is Stacey 
hours after leaving the resting spot.
According to the question.
Distance remaining = 
miles
Time taken = hours Speed maintained = 
mph
After leaving the resting spot she has covered a distance :
⇒ 
⇒ 
⇒ 
miles.
In hours she has covered 
miles and also she has covered 
miles before stopping here.
From the beginning she has covered :
⇒ 
⇒ 
miles.
Stacey is 16 miles far from the beginning of the trail.
Let's do the work shall we....
this is going to be a ratio problem.
Striped Marlin:
70 miles/ One hour (Or 60 minutes)
Sailfish:
40 miles/ 30 minutes.
Since 30 minutes is only one half of 60 minutes, all we have to do is multiply the sailfish ratio by 2 in order to receive the correct mph.
(40miles/30 minutes) x2 = (80 miles/60 minutes(or one hour)).
Therefore, the sailfish is faster! 80 miles per hour is faster than the 70 mph marlin.
