Answer:
Step-by-step explanation:
Given : For each sandwich:
Quantity of meat used = 4 ounces
Quantity of cheese used = 3 ounces
The combined ounces of meat and cheese are used on each sandwich =
Quantity of meat used + Quantity of cheese used
= 4 ounces + 3 ounces
= 7 ounces
Hence, The combined ounces of meat and cheese are used on each sandwich = 7 ounces
1 hour equals 60 minutes.
10 gallons per minute x 60 minutes = 600 gallons in 1 hour.
24 hours x 600 gallons per hour = 14,400 gallons in 24 hours.
Answer:
0.4
Step-by-step explanation:
x=2/5
2/5=0.4
Use this formula: distance = rate x time
so, distance=150km time= 7200 seconds which equals 2 hr rate= unknown
150= rate x 2 or 150= 2r
Now, rate= 150 divide by 2; therefore rate= 75 km/hr
the answer is the car travels 75 km per hr
