Explanation

Use the work formula: 

Workers × Days × Hours per day / Units = constant

Case 1: 

30 workers, 20 days, 8 hours/day, 3000 units

Case 2: 

32 workers, D days, 10 hours/day, 2000 units

So,

(30 × 20 × 8) / 3000 = (32 × D × 10) / 2000

4800 / 3000 = 320D / 2000

1.6 = 0.16D

D = 1.6 / 0.16 = 10

Speed = 200 km/hr

Time from 12:24 PM to 2:12 PM:

From 12:24 to 1:24 = 1 hour

From 1:24 to 2:12 = 48 minutes

Total time = 1 hour 48 minutes = 1 + 48/60 = 1.8 hours

Distance = Speed × Time

Distance = 200 × 1.8

Distance = 360 km

Given: 

y = 2x 

z = 5y

First find z in terms of x:

z = 5y = 5 _ (2x) = 10x

Now substitute in x + 3y + z:

x + 3y + z = x + 3_(2x) + 10x

= x + 6x + 10x

= 17x
