A military aircraft can travel 740 miles per hour. The distance between Tyndall Air Force Base in Florida and Lakenheath Air For
BARSIC [14]

Answer: 3.5 h

Step-by-step explanation:

<u>1. Data:</u>

a) s = 740 miles / h

b) d = 2,567 miles

c) t = ?

<u>2. Equation:</u>

  • speed = distance / time
  • s = d / t

<u>3. Solution:</u>

  • Solve the equation for t:

        s = d / t ⇒ t = d / s

  • Substitute values:

        t = 2,567 miles / (740 miles/h) ≈ 3.47 h ≈ 3.5 h

Reginald answered at 78% of the questions on his social studies quiz correctly what fractional part of the question did he not a
Otrada [13]

If Reginald answered 78% correctly out of a total 100%, we can subtract 78 from 100:

100 - 78 = 22

He answered 22% of the question incorrectly. But how do we find the bottom number? Remember what we said earlier. The <u>total</u> is 100%. He got 22% out of 100% wrong. Wouldn't that be \frac{22}{100}?

Now that we know our fraction, we can reduce it. Let's start by dividing our fraction in half:

\frac{22}{100} = \frac{11}{50}

Can we reduce that any more? No, because 11 can not be divided by anything else.

If you want the first fraction, go with \frac{22}{100}, but if they want a reduced fraction, then \frac{11}{50} would be best.
