Answer 1

1)76 умнож. на 3=228 проедет экспресс 2)228 умнож. на 4=912 проедет экспресс 3)76 на 4=304 проедет поезд 4)912-304=608 разница

Answer 2

Calculating the Distance Traveled by the Express Train

To calculate the distance traveled by the express train in 4 hours compared to the freight train in the same time, we can use the formula:

Distance = Speed × Time

Given: - Speed of the freight train = 76 kilometers per hour - Speed of the express train = 3 times the speed of the freight train - Time = 4 hours

Calculating the Speed of the Express Train

First, let's calculate the speed of the express train.

The speed of the express train is 3 times the speed of the freight train, which means the speed of the express train is:

76 km/h × 3 = 228 km/h.

Calculating the Distance Traveled by the Express Train

Now, we can calculate the distance traveled by the express train in 4 hours:

Distance = Speed × Time

Distance = 228 km/h × 4 h = 912 kilometers.

Conclusion

Therefore, the express train will travel 912 kilometers more than the freight train in the same 4-hour time period.
