Answer:
£166 : £581
Step-by-step explanation:
sum the parts of the ratio, 2 + 7 = 9 parts
Divide the amount by 9 to find the value of one part of the ratio
£747 ÷ 9 = £83 ← value of 1 part of the ratio, then
2 parts = 2 × £83 = £166
7 parts = 7 × £83 = £581
£747 = £166 : £581 in the ratio 2 : 7

Answer:
3.704 Hours
Step-by-step explanation:
This problem can be solved by using concept of relative speed. relative speed is speed of one body in comparison of other.
If two bodies are moving in same direction their relative speed is calculated by taking difference of each other speed.
If two bodies are moving in opposite direction their relative speed is calculated by taking sum of each other speed.
In the problem stated two bodies are moving in north and south direction, hence they are moving in opposite direction, thus their speed can be taken sum of individual speed.
which is
(60+65) Km/Hr = 135 km/hour
Now given in question distance between two bodies is 500 KM
and relative speed = 135 km/hour
using formula of speed distance and time
Time = distance / speed = 500/135 = 3.704 Hours
Therefore it will take 3.704 Hours for both of the trains to be 500 km apart.
Answer:
1. 32 inches = 81.28 centimeters
2.402 000 millimeters = 402 meters
3. 2.85 meters = 285 centimeters
4.2 kilometers= 2000000 millimeters
5. 71 meters = 0.071 kilometers
6. 8kg = 8000 g
7. 3000 g = 3 kg
8. 2.5 kg = 2500 g
9 850 mg = 9.85 g
10.75 dg = 1075 m
