[] To round, we look at the number right the place. If it is less than 5, keep it the same. If it is five or greater , round up.
[] In this case it is a 3, so we keep it the same. We get an answer of 68,500

Step-by-step explanation:
<u>Answer:</u>
Jet average speed was 45.5 miles per hour.
<u>Solution:
</u>
Given that a jet left airport and flew south. A passenger plane left one hour later flying at 52 miles per hour trying to catch up the jet.
After seven hours passenger plane caught up jet.
So distance travelled by passenger plane in 7 hours is same as distance travelled by jet in 7 + 1 = 8 hours as jet plane left 1 hour early.
<em>Distance travelled by passenger plane</em> = speed x time = 52 x 7 = 364 miles
So same distance that is 364 miles is travelled by jet plane in 8 hours.
=> Speed of jet = = 45.5 miles per hour.
Hence jet average speed was 45.5 miles per hour.
Simplifying
0.5p + -3.45 = -1.2
Reorder the terms:
-3.45 + 0.5p = -1.2
Solving
-3.45 + 0.5p = -1.2
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '3.45' to each side of the equation.
-3.45 + 3.45 + 0.5p = -1.2 + 3.45
Combine like terms: -3.45 + 3.45 = 0.00
0.00 + 0.5p = -1.2 + 3.45
0.5p = -1.2 + 3.45
Combine like terms: -1.2 + 3.45 = 2.25
0.5p = 2.25
Divide each side by '0.5'.
p = 4.5
Simplifying
p = 4.5
First lets change the fractions so they have common denominators:
3/5 = 6/10
The bank was 1/10, after adding the pennies it was 6/10
6/10 - 1/10 = 5/10 = 1/2
This means 400 pennies filled 1/2 the piggy bank.
There are 2 halves (1/2) to a whole ( full piggy bank).
The piggy bank can hold 400 x 2 = 800 pennies.
