Explanation

40 men finish the work in 25 days

Total work = 40 men * 25 days = 1000 man-days

Now, 25 men will finish the work:

1000 man-days / 25 men = 40 days

Explanation

"Have been trying" correctly uses the present perfect continuous tense to show an ongoing effort by multiple members.

The subject "many leading opposition party members" is plural, so the verb must also be in plural form.

Explanation

To find the average speed for the entire journey, let's assume the total distance traveled is 3x (since he travels equal distances at each speed).

Let's denote the speeds as:

S1 = 40 km/h

S2 = 30 km/h

S3 = 15 km/h

Time taken for each segment:

T1 = x / 40

T2 = x / 30

T3 = x / 15

Total time = T1 + T2 + T3

= x / 40 + x / 30 + x / 15

To find the common denominator (120):

Total time = 3x / 120 + 4x / 120 + 8x / 120

= 15x / 120

Total distance = 3x

Average speed = Total distance / Total time

= 3x / (15x / 120)

= 3 * 120 / 15

= 24

Explanation

Multiply both sides by 2:

$$|3x| = 6 Rightarrow 3x = ±6 Rightarrow x = ±2$$
