Question

Шерлок Холмс пустился вдогонку за преступником в 7 часов утра.Сможет ли он догнать преступника к 2 часам дня,если скорость Шерлока Холмса 8 км/ч,скоромть преступника 6 км/ч,а первоначальное расстояние 12 км?:

Answer 1

1) 14-7=7 сколько  часов  должен преодолеть Шерлок

2)7*8=56 км сколько он преодолеет за 7 часов

 

3) 7*6= 42км преодолеет преступник  за 7 часов

4)42+12=54 км пройдёт преступник вообще

56 больше 54

то есть   сможет догнать

Answer 2

To determine if Sherlock Holmes can catch up to the criminal by 2:00 PM, we need to calculate the time it would take for Sherlock Holmes to cover the initial distance of 12 km at a speed of 8 km/h, and compare it to the time it would take for the criminal to cover the same distance at a speed of 6 km/h.

Calculating the time it takes for Sherlock Holmes to cover the initial distance:

To calculate the time it takes for Sherlock Holmes to cover the initial distance of 12 km at a speed of 8 km/h, we can use the formula:

Time = Distance / Speed

Substituting the values, we get:

Time taken by Sherlock Holmes = 12 km / 8 km/h = 1.5 hours

Therefore, it takes Sherlock Holmes 1.5 hours to cover the initial distance of 12 km.

Calculating the time it takes for the criminal to cover the same distance:

To calculate the time it takes for the criminal to cover the same distance of 12 km at a speed of 6 km/h, we can use the same formula:

Time = Distance / Speed

Substituting the values, we get:

Time taken by the criminal = 12 km / 6 km/h = 2 hours

Therefore, it takes the criminal 2 hours to cover the same distance of 12 km.

Comparing the times:

Since Sherlock Holmes takes 1.5 hours to cover the initial distance and the criminal takes 2 hours to cover the same distance, we can conclude that Sherlock Holmes will not be able to catch up to the criminal by 2:00 PM. The criminal will have already covered the distance and moved further ahead.

Please note that this calculation assumes constant speeds and does not take into account any other factors that may affect the pursuit.
