7. B
Step-by-step explanation:
3. Every hour the car could travel 60 km. The question asked if in how many hours can the car cover a distance of 240 km so just simply divide 240 km by 60 km (car's travelling rate) and the answer would be 4 hours.
4. The train travels at 267.8 mph and you are asked to find the distance it can cover in 3 hours so just multiply it by 3. The answer is 803.4 miles.
5. First, you need to find the distance Juan covered for 3 hours at a rate of 60 kph, just multiply the time and the speed. Then, you need to find the distance Juan drove for 2 hours at a rate of 80 kmp, so just multiply them. Lastly, to find the average speed, add your results from the first and second equations and divide them by two. You'll get 68 km/h.
6. To find the are of the triangle we have the formula
. The area of the triangle here is 6 sq in. Since we have 3 triangles, just multiply your area by 3. The answer is 18 sq in.
7. First, find the area of the square and triangle. The area of the square is 16 sq dm and the area of the triangle is 10 sq dm. After this, just add the two areas to find the total area of the figure which is 26 sq dm.
