Question

80 км/ч-6 часов 120 км/ч- х часов

Answer 1

1)80 * 6 = 480 - за 6 часов при 80 км/ч
2)480 : 120 = 4 - часа

Answer 2

To find the value of "x" (the time in hours) when the speed is 120 km/h, you can use the formula:

Speed = Distance / Time

Given that the distance is constant, you can set up an equation using the two sets of data provided:

For the first set of data: Speed = 80 km/h Time = 6 hours

Distance = Speed × Time Distance = 80 km/h × 6 hours Distance = 480 km

Now, for the second set of data: Speed = 120 km/h Time = x hours (the unknown we need to find)

Again, use the formula to set up the equation: Distance = Speed × Time 480 km = 120 km/h × x hours

To find "x," divide both sides by 120 km/h: x = 480 km / 120 km/h x = 4 hours

So, when the speed is 120 km/h, it will take 4 hours to cover the same distance as it took 6 hours at 80 km/h.
