Answer 1

Answer:

1) 8.4 seconds

2) Arjun= ₹16,029

Rahul= ₹21,166.5

3) 50km

Step-by-step explanation:

1) Given: speed= 75 km/hr or 75×5/18

or 375/18 m/s

Total distance to be covered = 105+70

or 175 m

So, time= dis/sp or 175/375/18

or 8.4 seconds

2)Sum of ratios= 0.78+1.03

or 1.81

Let Arjun earns= 0.78x

and Rahul earns = 1.03x

So, 0.78x+1.03x= 37195.50

or 1.81x=37195.50

or x= 20,550

So, Arjun earns= 0.78x or 0.78×20550

or Arjun= ₹16029

and Rahul earns= 1.03x or 1.03×20550

or Rahul earns= ₹21166.5

3)Given: Total time taken:= 3.5 hours

Time spent at Panchla= 1 hour

Average speed= 40km/hr

So, time spent while travelling= 3.5-1= 2.5 hours

Total distance covered in going to panchla and coming home = 2.5×40

or 100km

So, the distance between Panchla and home= 100/2

or 50km
