Answer:
Megan travelled at 9mph for 6 hours and 7mph for 3 hours
Step-by-step explanation:
Speed = distance / time
Speed*time = distance
Assuming that Megan travelled x hours at 9mph
(9*x) + (7*(9-x)) = 75
x = 6 hours
So Megan travelled at 9mph for 6 hours and 7mph for 3 hours
Answer:
14
Step-by-step explanation:
when rounding you round up when the number is 5+ but if it's anything below 5 you go down instead, making this answer being 14
Answer:
Step-by-step explanation:
<h3>Given </h3>
<h3>To find</h3>
<h3>Solution</h3>
- 5x:9=7:3
- 5x = 7*9/3
- 5x = 7*3
- 5x = 21
- x = 21/5
- x = 4.2
Answer:
Continuous
Step-by-step explanation:
The rate of flow of water down the river is referred to as its speed. Thus the speed changes with respect to the distance covered. Which implies that there is a direct relationship between the distance covered (in miles) by the water flow and time taken (in hours).
The relationship between hours and miles the water traveled is continuous.
From the figure, we can conclude that the little triangle is an isosceles triangle, the greatest angle is 90 because ∠A = 90 and they are supplementary, therefore, using the triangle sum theorem:
