Answer:
6 hours
Step-by-step explanation:
Total time it will take to complete the trip = Total time spent on riding + Time taken for lunch break.
Distance to be covered = 60 miles.
D = 60
Speed of riding = 15 miles per hour
S = 15
Thus time taken to cover a distance 60 miles by riding at a speed of 15 mph:
T=D/S=60/15
T= 4hours
They will spend 4 hours on riding and 2 hour of lunch break.
Hence total time taken to complete the trip = 4 + 2 = 6 hours.
It will take 6 hours to complete the trip.
I'm guessing it represents the perimeter.
Answer:
1. 1/2 or .5 (same thing)
2. 1
3. -4k
4. 28n^5
Step-by-step explanation:
1.
2/2^2 → 2/4 = .5
2.
3^4/3^4 → 81/81 = 1
3.
3k^2/7k = -4k
4.
7n^4 x 4n = 28n^5
a.) you start with 19=h/3-8 so you add 8 to both sides then you simplify 19+8 to 27 so the equation then becomes 27=h/3 from there you multiply each side by 3 so its 27*3=h then you simplify 27*3 which leaves you with 81=h u then switch it around and your final answer h=81
b.) you start with 0.6x +0.8=1.4 first you subtract 0.8 from both sides so the equation is 0.6x=1.4-0.8 then you simplify 1.4-0.8/ so it then becomes 0.6x=0.6 u then divide both sides by 0.6 so the equation is now x=0.6/0.6 you then simplify 0.6/0.6 so you are left with x=1
