Answer:
B) 
Step-by-step explanation:
First simplify the radical on the right.
is equal to 
, because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.
Then we know 
is just equal to 25, which means the simplified version of is 
.
Then we can use this new representation to finish solving.
, so the answer would be B

Answer:
60 km/h
Step-by-step explanation:
Let us use the x to represent the speed of the car since it is the smaller value.
Then, the distance covered by the car is 4x since was going 4 kph.
The distance covered by the train is (x+5) times 7 or 7x+35.
We know that the total distance covered is 640 km.
Using this information, we can set up the equation 4x+7x+35=640.
By subtracting both sides by 35 and combining the x's, we get a new equation of 11x=605.
After this, we divide both sides by 11 and get x=55.
Lastly, we add 5 to 55 since the train is 5 km faster than the car and that x stood for the car.
Train=60 km/h
