Answer:
322 1/2 miles
Step-by-step explanation:
Recall how s = d/t ; speed = distance/time.
To effectively solve for distance traveled, rearrange the formula so that distance is on the left-hand side by multiplying speed, and time.
speed × time = distance/time × time
speed × time = distance
distance = speed × time ; d = st.
Now to find the total distance traveled, individually multiply the rate of speed with the time. Time will cancel, and we will get the total mileage.
Given an average speed of 60 mph at a certain time for 4.5 hours, and another average speed of 35 mph at another time of 1.5. Calculate the distance individually, and then add both distances together. Distance 1 = 60 mph × 4.5 h = 60 miles / h × 4.5h = 60 miles × 4.5 = 270 miles.
Distance 2 = 35mph × 1.5h = 35 miles / h × 1.5h = 35 miles × 1.5 = 52 1/2 miles.
Distance 1 + Distance 2 = Total distance.
270 miles + 52 1/2 miles = 322 1/2 miles.
Answer:
F = 2
Step-by-step explanation: If you want to know which one is a solution, you have to substitute the numbers in for F.
F = 7:
3 > f
3 > 7
This is false because 3 is NOT greater than 7, it is less than 7.
F = 9:
3 > f
3 > 9
This is false because 3 is NOT greater than 9, it is less than 9.
F = 2:
3 > f
3 > 2
This is TRUE because 3 IS greater than 2.
Hope this help you!!! :)
Answer:
7.8-9.3n
Step-by-step explanation:
2.8-5.3n - 4n + 5
Combine like terms
2.8 +5 -5.3n -4n
7.8-9.3n
x-4>15.5
x>15.5+4
x>19.5
i suppose the answer is D since it is the closest to ^.
