Problem Analysis

We are given that a truck and a car left a bus station simultaneously in opposite directions. The truck traveled 70 km, and the car traveled 140 km. We are also given that the speed of the truck is 35 km/h. We need to find the speed of the car.

Solution

To find the speed of the car, we can use the formula:

Speed = Distance / Time

We know the distance traveled by the car is 140 km. We need to find the time taken by the car to cover this distance.

Let's calculate the time taken by the truck to cover 70 km using the formula:

Time = Distance / Speed

Substituting the values, we get:

Time taken by the truck = 70 km / 35 km/h = 2 hours

Since the truck and the car left the bus station simultaneously, the time taken by the car to cover 140 km would also be 2 hours.

Now, we can find the speed of the car using the formula:

Speed of the car = Distance / Time

Substituting the values, we get:

Speed of the car = 140 km / 2 hours = 70 km/h

Therefore, the speed of the car is 70 km/h.

Answer

The speed of the car is 70 km/h.
