Let H be the total height of rock wall.

We have been given that after one minute we climb half of the rock wall \frac{H}{2} and after another minute we climb half of the remaining height that is \frac{1}{2}\cdot \frac{H}{2}.

We are also given that after two minutes we are 24  feet above ground. To figure out total height (H) of the rock wall we will substitute our given information in an equation.

\frac{H}{2}+\frac{1}{2}\cdot \frac{H}{2}=24\text{ feet}\\

Now we will solve for H.

\frac{H}{2}+ \frac{H}{4}=24\text{ feet}\\
\\
\frac{2H}{4}+\ \frac{H}{4}=24\text{ feet}\\
\\
\frac{3H}{4}=24\text{ feet}

H=\frac{24\cdot 4}{3}\\
\\
H=8\cdot 4=32

Therefore, total height (H) of rock wall is 32 feet.

(1/2)H+(1/2)×(1/2)H=24
(1/2)H+(1/4)H=24
(3/4)H=24
H=32

Tom wants to drive to his friend's house. If he drives 359 miles a day, how long will it take him to drive 1,462 miles? Round to
agasfer [191]

Answer:

5 days

Step-by-step explanation:

Speed = 359 miles/day

Distance = 1,462 mile

Use this formula to calculate time ( in number of days);

Time = Distance / speed

Next, plug in the numbers given into the formula to calculate time;

Time = 1462 / 359 = 4.0724

Since you are told to round off in days, you will round up 4.0724  to 5 days.

Therefore, it will take Tom 5 days to drive 1,462 miles.
