Question

Пешеход за 3 что прошёл 10,5 км. сколько км пути он пройдёт за 4,5 ч , двигаясь с той же скоростью?

Answer 1

T=3ч s=10,5 км
 v= 10,5:3=3,5 км\ч
 за 4 часа он пройдет 3,5*4= 14 км

Answer 2

1) 10,5:3= 3.5 (км/ч) - скорость пешехода;
2) 3,5*4,5=15,75 (км) - пройдет пешеход за 4.5 часа

Answer 3

Calculation of Distance Traveled

To calculate the distance traveled by a pedestrian in 4.5 hours, assuming they maintain the same speed as when they covered 10.5 km in 3 hours, we can use the formula:

Distance = Speed × Time

Given that the pedestrian covered 10.5 km in 3 hours, we can calculate their speed:

Speed = Distance / Time

Substituting the values, we have:

Speed = 10.5 km / 3 hours

Calculating the speed:

Speed = 3.5 km/h Now, we can calculate the distance traveled in 4.5 hours using the speed we just calculated:

Distance = Speed × Time

Substituting the values:

Distance = 3.5 km/h × 4.5 hours

Calculating the distance:

Distance = 15.75 km

Therefore, the pedestrian will cover a distance of 15.75 km in 4.5 hours, assuming they maintain the same speed as before.
