Answer:
speed of Jada = 6km per hour which is not equal to
speed of Andre = 8km per hour
They did not run at same speed
Step-by-step explanation:
formula of speed = distance covered/ time taken
For Andre
Distance = 2 KM
time = 15 mins
60 mins = 1 hour
15 mins = 1/60 * 15 hour = 0.25 hours
thus,
speed = 2km/0.25 hour = 8 km per hour
Similarly for Jada
Distance = 3 KM
time = 20 mins
60 mins = 1 hour
20 mins = 1/60 * 20 hour = 1/3 hours
thus,
speed = 2km/(1/3)hour = 6 km per hour
Now we have
speed of Jada = 6km per hour which is not equal to
speed of Andre = 8km per hour
Answer:
Option C
Step-by-step explanation:
The given inequality is
5x-1 < 19 and 
Group similar terms to get:
5x < 19+1 and 
5x < 20 and 
Solve for x to get:
x < 4 and 
The correct choice is C
Answer:$400
Step-by-step explanation:
Let them original price be cp
Selling price=340
Percentage decrease=15
Percentage decrease=(cp-sp)/sp x 100
15=(cp - 340)/cp x 100
Cross multiplying
15cp=100(cp-340)
Opening brackets
15cp=100cp-34000
Collect like terms
100cp-15cp=34000
85cp=34000
Divide both sides by 85
85cp ➗ 85=34000 ➗ 85
cp=400
