2)80:2=40

3)400:40=10

4)480:40=12

Answer 3

Calculation of Travel Time for Each Car

To calculate the travel time for each car, we need to determine the speed at which they were traveling. Since both cars were traveling at the same speed, we can use the formula:

Speed = Distance / Time

Let's denote the speed of both cars as 's' and the time taken by the first car as 't'. We are given that the first car traveled a distance of 400 km and the second car traveled a distance of 480 km, which means:

s * t = 400 (Equation 1)

We are also given that the second car was on the road for 2 hours longer than the first car. Therefore, the time taken by the second car can be expressed as 't + 2'. Using the same speed 's', we have:

s * (t + 2) = 480 (Equation 2)

To solve this system of equations, we can substitute Equation 1 into Equation 2:

400 + 2s = 480

Simplifying the equation, we get:

2s = 80

Dividing both sides by 2, we find:

s = 40

Now that we know the speed of both cars, we can substitute this value back into Equation 1 to find the time taken by the first car:

40 * t = 400

Simplifying the equation, we get:

t = 10

Therefore, the first car was on the road for 10 hours, and the second car was on the road for 10 + 2 = 12 hours.

So, each car was on the road for 10 hours and 12 hours respectively.
