B. 48.7
C. 52.9
D. 56.4
Answer:
The correct answer is D. 56.4
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Kilometers hiked by Jason on Saturday = 15.6
Kilometers hiked by Jason on Sunday = 18.1
Kilometers hiked by Jason on Monday = 22.7
2. How many kilometers did he hike during the three days?
Total of kilometers hiked by Jason = Kilometers hiked by Jason on Saturday + Kilometers hiked by Jason on Sunday + Kilometers hiked by Jason on Monday
Total of kilometers hiked by Jason = 15.6 + 18.1 + 22.7
Total of kilometers hiked by Jason = 56.4
Average speed = Total distance/Total time.
First drive:
120/60=2 (distance/rate=time)
Second drive:
120/40=3 (distance/rate=time)
Average:
Total time=120+120=240
Total time=3+2=5
Average speed = Total distance/Total time=240/5=48
His average speed was 48 mph.
Answer:
Let x = the number
5x-14 = 3x
-14 = 3x-5x
-14 = -2x
-14/(-2) = x
7 = x
The number is 7.
A. -w/2=11
B. -1/6x=-3
C.-4=v/(-10)
D. -3/4 2=8
The answer is A and D :)))))))))
