Question

Из 2 городов одновременно навстречу выехали 2 велосипеда со скоростями 14.5 км/ч и 16.5 км/ч. через 0.7 часов расстояние между ними составляло 96.2 км. найти расстояние между городами. помогитеее плиииз

Answer 1

Эт слишком просто у меня получилось, поэтому я не уверена
1) 14.5•0.7=10.15 - прошел 1 велосипедист
2) 16.5•0.7=11.55 - прошел 2 велосипедист
3) 10.15+11.55+96.2=117.9 - расстояние иежду городами

Answer 2

Problem Analysis

We are given that two bicycles start simultaneously from two cities and travel towards each other. The first bicycle has a speed of 14.5 km/h, and the second bicycle has a speed of 16.5 km/h. After 0.7 hours, the distance between them is 96.2 km. We need to find the distance between the two cities.

Solution

Let's assume that the distance between the two cities is d km.

We can use the formula: distance = speed × time to find the distance traveled by each bicycle.

The first bicycle travels at a speed of 14.5 km/h for 0.7 hours, so the distance it covers is 14.5 km/h × 0.7 h = 10.15 km.

The second bicycle travels at a speed of 16.5 km/h for 0.7 hours, so the distance it covers is 16.5 km/h × 0.7 h = 11.55 km.

Since the total distance between the two bicycles is 96.2 km, we can set up the equation:

10.15 km + 11.55 km = 96.2 km

Simplifying the equation, we get:

21.7 km = 96.2 km

To find the distance between the two cities, we can solve for d:

d = 96.2 km

Therefore, the distance between the two cities is 96.2 km.

Answer

The distance between the two cities is 96.2 km.
