A marathon is 26.2 miles. If Sally ran a marathon in 3 hours and 3 minutes, what was her approximate pace?
1 answer:
<span>A marathon is 26.2 miles which mean the distance = 26.2 miles
</span>
Sally ran a marathon in 3 hours and 3 minutes which mean the time taken to finish the marathon = 3 hours and 3 minutes
∴ distance = 26.2 miles
time = 3 hours and 3 minutes = 3 + 3/60 = 3.05 hours
∴ <span>the approximate pace = speed =
</span>
∴ <span>the approximate pace = 26.2/3.05 ≈ 8.59 miles per hour
</span>
∴ The answer is <span>her approximate pace = 8.59 mile/h

Answer:
Malik substituted 60 for y instead of x.
Step-by-step explanation:
According to the given situation the computation of error that Malik make first when solving the equation is shown below:-
First, we will find the value of x
x = 625
Now, we have
we will solve the above equation, to find the value of y
24 - 4y = 10
4y = 24 - 10
4y = 14
So, from the above calculation, the correct option is
Malik substituted 60 for y instead of x.
