Answer:

1. 25 × 1000/60

= 2500/6

2.For 55 km 1 hour

So for 120 km -. x hours.

x hours = 120/

x = 24/11 hours.

3. Total time = 5 hrs.

For 3 hrs it travels with speed of 60 km/he

So the distance travelled will be 180 kms.

The remaining distance to be covered is 120 kms and remaining time is 2 hrs .So the required speed wil be 120/2 = 60 km /hr. So the car can travel with same speed

4.Speed of first car is 240/4 = 60 km/hr

Speed of second car is 50 km/hr.

Distance to be covered is 240 kms.

We know that speed = distance /time

So time = distance / speed

Thus time = 240/ 50

= 4.8 hours.
