Answer:
376 inches^2
Step-by-step explanation:
<h3>1. Divide up each type of rectangle </h3>
- 10x6
- 6x8
- 8x10
<h3>2. Find the area of each rectangle</h3>
- 10x6=60
- 6x8=48
- 8x10=80
<h3>3. Multiply each rectangle by two to get the opposite one</h3>
- 60x2=120
- 48x2=96
- 80x2=160
<h3>4. Add them together</h3>
120+96+160=376
The surface area is 376 inches^2

Answer:
232 miles had travelled when Houa fell asleep.
Step-by-step explanation:
1. .29 x 800 = 232
Taking into account the supplied speeds, Boston is from the destination to:
<h3>
Calculation of the
distance between
Boston and Place of
Destination</h3>
To identify the distance between Boston and the destination of the trains, it must be remembered that the <u>speed</u> mentioned for each one is a reference to the distance traveled per hour, therefore, after each hour, each train will travel :
- Regular train: 60 miles
- Express train: 80 miles
According to the information given, when the express train leaves, the regular train has a 60-mile lead, which is getting shorter hour by hour because the express train travels 20 miles per hour more than the normal train.
Therefore, in <u>three hours</u>, the express train would catch up with the regular train, calculating the distance thanks to the speed formula:
And clearing the distance:
Therefore, the destination would be <u>240 miles</u> from Boston, which would take four hours by regular train and three hours by express train.
