Answer:
80 minutes
Step-by-step explanation:
1. Determine the volume of the tank
volume = length x width x height
100 cm = 1 meter
80cm /100 = 0.8m
1.2 x 1 x 0.8 = 0.96m³
2. convert litre to meter
1 liter = 0.001 m
2 litres = 0.002m
3. determine the time it would take to fill 0.96m
(0.96x 10) / 0.002 = 4800 seconds
4. convert seconds to minutes
60 seconds = 1 minute
4800 seconds / 60 = 80 minutes
2l = 0.0
Answer:
1 hour
Step-by-step explanation:
Lea's speed = 22km/hr
Trevon's speed = 43km/hr in a direction opposite Lea's
How long does Trevon needs to drive before they are 65km apart.
Note : both took at the same time and in opposite direction.
Recall : speed = distance / time
Distance = speed * time
Distance between them = 65km
Let Trevon's distance = D2 = 43 * t
Lea's distance = D1 = 22 * t
t is the same since they both left at the same time.
D2 + D1 = 65
43t + 22t = 65
65t = 65
t = 65/65
t = 1 hour
Answer:
341 meters
Step-by-step explanation:
you just multiply 31 by 11.
Math uses numbers and equations, and science requires the scientific method and experimentation
