Answer:

9.8

Step-by-step explanation:

<em>updated</em>

9^2=x^2+4^2

9*9=x*x+4*4

81=x*x-16

+16. +16

97=x*x

Leona [35]

Answer:

Thomas travels <em>64 miles each hour</em>.

Step-by-step explanation:

Distance traveled by train = 328 miles

Time taken to travel by train = 5\frac{1}{8} hr \Rightarrow \frac{5 \times 8+1}{8} \Rightarrow \frac{41}{8} hr

We know that speed can be formulate as:

\text{Speed = } \dfrac{\text{Distance Travelled}}{\text{Time Taken}}

Speed is equal the total distance traveled for the one unit time.

In our case, speed is total distance traveled in miles in 1 hour.

So, using above formula:

\text{Speed = } \dfrac{328}{\dfrac{41}{8}}\\\Rightarrow 8 \times 8\\\Rightarrow 64\ miles/hour

As per definition of Speed, Thomas travels <em>64 miles each hour</em>.
