Answer:
D.
Step-by-step explanation:
Answer:
L=8
Step-by-step explanation:
S=smaller number
L=larger number
S+L=5 : S=5-L
L=14+2S
substitute for S:
L=14+2(5-L)
solve for L:
L=14+10-2L
3L=24
L=8
Answer:
Step-by-step explanation:
Average speed = total distance / total time taken
Average speed is the total distance traveled divided by the total time taken
The carrier first odometer route is
d_1 = 31,500 miles
On return of the truck, the odometer reads
d_2 = 31,713 miles
The total time taken is 6.5 hours on return
Then,
Average Speed = total distance / total time.
A.V = (d_1 + d_2) / t
A.V = (31,500 + 31713) / 6.5
A.V = 63213 / 6.5
A.V = 9725.1 mile per hour
A.V = 9725.1 mph
