Answer 1

I’m not sure about it please check it on the internet

Answer 2

The difference between the time taken by them to reach their destination from point C will be 6 hours.

Step-by-step explanation:

Sita is moving at a speed of 40 km/hr from A to B.

Again, Gita is moving at a speed of 60 km/hr from B to A, then after 2 hours, Gita will reach a distance (2 × 60) = 120 km. from B.

So, the remaining (480 - 120) = 360 km they will move towards each other.

The resultant speed of Sita and Gita is (40 + 60) = 100 km/hr.

So, the remaining 360 km they will cover in $\frac{360}{100} = 3.6$ hours to reach point C.

Now, Gita will move by (60 × 3.6) = 216 km and Sita will move by (360 - 216) = 144 km from A.

Therefore, the distance from C to A is 144 km which Gita will cover is $\frac{144}{60}= 2.4$ hours and the distance from C to B is (216 + 120) = 336 km which Sita will cover in $\frac{336}{40} = 8.4$ hours.

Therefore, the difference between the time taken by them to reach their destination from point C will be (8.4 - 2.4) = 6 hours. (Answer)
