A ship left port a with a speed of 40 mph. in 1.25 of an hour, a second ship left the port with a speed of 60 mph. in how many hours and at what distance from port a will the second ship catch up with the first one

In 1.25 hrs, the first ship went 50 miles. This is the distance between the two ships. So, at the start of the second ships journey, it has to catch up with the other one that is 50 miles away. It is going 20 mph faster than ship 1. 50 divided by 20 is 2.5 hours. 60 times 2.5 hours is 150 miles. So at 150 miles in 2.5 hours, the two ships will be at the exact same spot.

Is known :

First boat speed = 40 mph

Within 1.25 hours the second ship left the port with a speed of 60 mph

Asked: How many hours and how far from the port of the second ship will follow?

Settlement:

Calculate the mileage of the first ship in 1.25 hours

distance = 1.25 x 40

Mileage = 50 miles

Within 1.25 hours the first ship had covered 50 miles

Calculate the distance between the first ship and the second ship

Distance of ships 1 & 2 = 50: 20

Distance of ships 1 & 2 = 2.5 hours

Note: 20 is the difference in the speed of ships 1 & 2.

Calculate the distances of ships 1 & 2 will meet

Distance of ships 1 & 2 = 60 x 2.5

Distance of ships 1 & 2 = 150 miles.

So ship 1 and ship 2 will meet in 2.5 hours and within 150 miles of the port.

Further explanation

Comparison is the difference (difference) of two or more things by following certain patterns of similarity. So, the definition of comparison is essentially different but has similar types of patterns. In general, comparisons can be grouped into two parts, Comparison of Values and Comparison of Values.

A. Value Comparison

Value comparison is the comparison of two or more values of a similar quantity that has the same value or price. If the value of one component rises, the other components will also increase.

B. Comparison of Value Turns

A comparison of reversing values is the comparison of two values of a similar quantity where the more the value of one component increases, the other components will decrease further.
