Answer:
direct relation between distance travelled by a train and its speed, when time is constant.
Step-by-step explanation:
We know that the speed of an object is the total distance covered divided by total time taken. Mathematically, it is given by :
Where
d is distance
t is time taken
It can be seen that relation between the distance and the speed is direction. Hence the correct option is (a) "direct".
Arthimetic sequence so use the formula
True because tan(20)=2.1 and cot(20)=is o.44
So the the answer would be calculated in this way: 10*11/100 + 6*7/100 = 110/100 + 42/100 = 1.1 + 0.42 = 1.52
Answer: 1.52 gallons
