Answer:
50 weeks
Explanation:
Given that :
ROY:
Initial weight = 150 pounds
Weight loss per week = 1.5 pounds
LUIS:
Initial weight = 200 pounds
Weight loss per week = 2.5 pounds
Let x = Number of weeks
Number of weeks when both Luis and Roy will weigh the same:
150 - 1.5x = 200 - 2.5x
-1.5x + 2.5x = 200 - 150
x = 50
Hence, Roy and Luis will weigh the same after 50 weeks
Answer:
The speed of the airplane is approximately 770 km/h (214 m/s).
Explanation:
Speed = 
Distance = 3080 km
Time = 4 hours
speed = 
= 770
speed = 770 km/h
The speed of the airplane is 770 km/h.
OR
Distance = 3080 km
But,
1 000 m = 1 km
3080 km = 3080000 m
distance = 3080000 m
Time = 4 hours
60 seconds = 1 minute
60 minutes = 1 hour
Thus, 4 hours = 60 x 60 x 4
= 14400 seconds
Therefore,
speed = 
= 213.8889
speed ≅ 214 m/s
The speed of the airplane is approximately 214 m/s.
