Question

Велосипедист був у дорозі 6 год, а мотоцикліст- 2 год.Хто з них подолав більшу відстань і на скільки кілометрів, якщо велосипедист їхав зі швидкістю 12 км/год, а мотоцикліст - 45 км/год? "

Answer 1

1) 12 * 6 = 72 (км) — проїхав велосипедист за 6 годин
2) 45 * 2 = 90 (км) — проїхав мотоцикліст за 2 години
3) 90 — 72 = 18 (км) — проїхав більше мотоцикліст
Відповідь: мотоцикліст проїхав на 18 км більше, ніж велосипедист.

Answer 2

Calculation of Distance Traveled

To determine who traveled a greater distance and by how much, we need to calculate the distances traveled by the cyclist and the motorcyclist.

The formula to calculate distance is:

Distance = Speed × Time

Let's calculate the distances traveled by both the cyclist and the motorcyclist.

For the cyclist: - Time = 6 hours - Speed = 12 km/h

Using the formula, we can calculate the distance traveled by the cyclist:

Distance_cyclist = Speed_cyclist × Time_cyclist

Distance_cyclist = 12 km/h × 6 hours

Distance_cyclist = 72 km

For the motorcyclist: - Time = 2 hours - Speed = 45 km/h

Using the formula, we can calculate the distance traveled by the motorcyclist:

Distance_motorcyclist = Speed_motorcyclist × Time_motorcyclist

Distance_motorcyclist = 45 km/h × 2 hours

Distance_motorcyclist = 90 km

Comparison of Distances Traveled

Now that we have calculated the distances traveled by both the cyclist and the motorcyclist, we can compare them.

The cyclist traveled a distance of 72 km, while the motorcyclist traveled a distance of 90 km.

Therefore, the motorcyclist traveled a greater distance by 18 km.
