Answer:
12.63 km/hr
Step-by-step explanation:
Given the distance=240km
At 12 km/hr it will take =240/12 =20
time for Express train = 20-1=19
speed=240/19=12.63...km/hr

Answer: a = 37, b=2 and c=2.</h3>
Step-by-step explanation: Given expression 7 + 9/4.
Let us simplify given sum of fractions by taking common denominator, we get
Common denominator is 4.
Therefore, multiplying top and bottom of 7/1 by 4, we get
.
We got same denominators,
So, combining top numbers, we get
We can read 37/4 as 37 divided by 4.
Therefore, 37 ÷ 4.
Let us write 4 as the power of 2.
37 ÷
On comparing c÷a^b and 37 ÷ 2^2, we can see..
<h3>a = 37, b=2 and c=2.</h3>
Answer:
I believe it would be 90
Step-by-step explanation:
First we compute the distance between the center and the given point which is exactly the radius
r =
Now that we know the center and the radius, we can write the equation of a circle with given radius and center:
where (h,k) represent the coordinates of the center (3,7).
We substitute and obtain
