1.	Solve the problems.1. Divide 4800 among Sama, Roshan and Ananya in the ratio 4 : 5 : 6.2. A train travels 1000km in 5 hours. How much will it travel in 3 hours?3. The value of a in a : 30 : : 7 : 15 is ?4. If A : B = 3 : 5 and C : B = 1 : 5 then what is A : C5. compare :4:5 and 3:4
Answer» Step-by-step explanation: 1. Let A=6x, B=5x,C=4x 15x=4800 x=320 Difference between shares of A and C =6x−4x =2x =2×320=Rs.640 2. A train travels 120 km in 2 hours and 30MINUTES. What is its average SPEED? We know Speed = distance/time Distance = 120 km Time = 2 hours 30 MINUTES = 2.5 hours Average Speed = to FIND out Average Speed = 120 km/ 2.5 hour Average Speed = 48 km per hour The average speed of the train is 48 km/hour Answer :The average speed of the train is 48 km/hour

Answer»

Step-by-step explanation:

1. Let A=6x, B=5x,C=4x

15x=4800

x=320

Difference between shares of A and C

=6x−4x

=2x

=2×320=Rs.640

2. A train travels 120 km in 2 hours and 30MINUTES. What is its average SPEED?

We know Speed = distance/time

Distance = 120 km

Time = 2 hours 30 MINUTES = 2.5 hours

Average Speed = to FIND out

Average Speed = 120 km/ 2.5 hour

Average Speed = 48 km per hour

The average speed of the train is 48 km/hour

Answer :The average speed of the train is 48 km/hour
