Question

Задача: Женис и Болат поехали на велосипедах в соседнюю деревню . Женис ехал со скоростью 7 км/ч,а Болат - со скоростью,меньшей на 3 км/ч.На сколько км больше проедет Женис,чем Болат , за 2 ч?

Answer 1

1) 7-3=4(км/ч)- скорость Болата
2) 7*2-3*2=8(км)- больше

Answer 2

Problem:

Женис и Болат поехали на велосипедах в соседнюю деревню. Женис ехал со скоростью 7 км/ч, а Болат - со скоростью, меньшей на 3 км/ч. На сколько км больше проедет Женис, чем Болат, за 2 ч?

Solution:

To find out how much further Zhenis will travel compared to Bolat in 2 hours, we need to calculate the distance each of them will cover in that time.

Let's start by calculating the distance Zhenis will cover in 2 hours. Since Zhenis is traveling at a speed of 7 km/h, we can use the formula:

Distance = Speed × Time

Substituting the values, we get:

Distance Zhenis = 7 km/h × 2 h

Simplifying the equation, we find:

Distance Zhenis = 14 km

Now, let's calculate the distance Bolat will cover in 2 hours. Bolat is traveling at a speed that is 3 km/h slower than Zhenis, so his speed is 7 km/h - 3 km/h = 4 km/h.

Using the same formula as before, we can calculate Bolat's distance:

Distance Bolat = 4 km/h × 2 h

Simplifying the equation, we find:

Distance Bolat = 8 km

To find out how much further Zhenis will travel compared to Bolat, we subtract Bolat's distance from Zhenis's distance:

Difference = Distance Zhenis - Distance Bolat

Substituting the values, we get:

Difference = 14 km - 8 km

Simplifying the equation, we find:

Difference = 6 km

Therefore, Zhenis will travel 6 km further than Bolat in 2 hours.

Answer:

Женис проедет на 6 км больше, чем Болат, за 2 часа.
