To solve this problem, we know that the formula for average
speed is:
average speed = total distance travelled / total time
Now let us first calculate for the total distance
travelled. Calculating:
total distance travelled = (70 km / hr) * 2 hr + (63 km /
hr) * 5 hr
total distance travelled = 140 km + 315 km
total distance travelled = 455 km
Now for the total time:
total time = 2 hours + 5 hours
total time = 7 hours
Hence, the average speed is therefore:
average speed = 455 km / 7 hours
<span>average speed = 65 km / hr</span>

Step-by-step explanation:
You can write it several ways. Here are two:
1) Proportion
160/1.00=x/0.95
(160 is the whole, 1.00 or 100%, and x is 95% of the whole. Solve for x.)
x=<u>160*0.95<em /></u> = 152/1 = 152<u>
</u> 1.00
2) Simple multiplication expression
"of" in math almost always means "multiply"
95% becomes 0.95. Multiply 0.95 by 160 to get your answer.
0.95*160=152
Either way, you get <u><em /></u><em />152, so that is your final answer.
The interest that Marcos will get is 50000.
<h3>How to calculate the interest?</h3>
The following can be deduced from the information given:
Principal = 50000
Interest rate = 12.5%
Time = 8 years
The simple interest will be:
= (PRT/100)
= (50000 × 12.5 × 8)/100
= 50000
The amount that will be obtained after 8 years will be:
= Principal + Interest
= 50000 + 50000
= 10000

Answer/Step-by-step explanation:
The reasons for the stated numbered angles that are congruent to the given angles are written in the parentheses as follows:
7. <7 ≅ 65° (alternate interior angles)
<4 ≅ 65° (corresponding angles)
<1 ≅ 65° (vertical angles)
8. <4 ≅ 51° (alternate interior angles)
<5 ≅ 51° (corresponding angles)
<7 ≅ 51° (vertical angles)
9. <1 ≅ 120° (corresponding angles)
<3 ≅ 120° (alternate angles)
