Answer:
With wind = 1000 km /hr
In calm air = 800 km/hr
Step-by-step explanation:
With wind :
Distance traveled = 1500 km
Time taken = 1.5 hours
Speed of plane in air :
Speed = distance / time
Speed = 1500 km / 1.5 hours
Speed = 100 km pe hour
In calm air :
Time taken = 1.875 hours
Distance = 1500 km
Speed of wind in calm air :
Distance / time
1500 km / 1.875
= 800 km/hr
Answer : 137.25
Step 1 - Convert the base of a triangle to decimal form
15 1/4 = 15.25
Step 2 - Multiply base by height
18 * 15.25 = 274.5
Step 3 - Divide 274.5 by 2
274.5 ÷ 2 = 137.25

Answer:
M ≥ -5 3/5
Step-by-step explanation:
-5(M+1)≤23
Distribute -5
-5M -5 ≤23
Add 5 to each side
-5M -5+5 ≤ 23 +5
-5M ≤ 28
Divide each side by -5, remembering to flip the inequality
-5M/-5 ≥ 28/-5
M ≥ -28/5
M ≥ -5 3/5
