Question

Один лыжник прошел дистанцию за 89 минут а другой за 1 час 30 минут кто из них раньше пришел к финишу и на сколько он опередил соперника

Answer 1

1 лыжник – 89 мин.
2 лыжник – 1 ч. 30 мин = 60+30=90 мин.
1 лыжник пришел раньше на 1 мин.

Answer 2

1 час = 60 мин 
1 ч 30 мин = 90 мин
90 - 89 = 1
первый опередил соперника на 1 мин  

Answer 3

Calculating the Finish Time of Skiers

To determine who finished the race earlier and by how much, we can convert the times for both skiers into a common unit and then compare them.

The first skier took 89 minutes to complete the race, while the second skier took 1 hour 30 minutes (which is equivalent to 90 minutes).

Comparing Finish Times

To compare the finish times, we can see that the first skier took 89 minutes, while the second skier took 90 minutes. Therefore, the first skier finished the race earlier by 1 minute.

So, the first skier finished the race earlier by 1 minute.
