Question

A boat covers 15 km in 3 hours, what distance can it cover in 2 hours and 30 minutes?

Answer 1

Answer:

Hence boat will cover a distance of 12.5 Km in 2 Hr 30 min

Step-by-step explanation:

In context to questions asked

We have to determine the value of distance covered by boat in 2 Hour 30 min

As per questions

We have

Boat cover 15 Km in 3 Hr

So, for determining the distance covered in 1 Hour we will divide 15 by 3

Thus distance covered in 1 Hour will be,

$\frac{15}{3} = 5 \: km$

So for determining the distance covered in 2 Hour 30 min we will multiply the time period by 5

As we know that

60 Min = 1 Hr

So, 30 min = 0

t Hr

So, 2 Hr. 30 min = 2.5 Hr

Hence distance covered in 2.5 Hr will be,

$5 \times 2.5 = 12.5 \: km$

Answer 2

Answer:

12.5 km

Step-by-step explanation:

According to the information provided in the question it is given as

Boat covers 15km in 3 hours

We need to find the distance covered in 2 hours and 30 minutes

Here  for finding first make an equation

As 2 hours 30 minutes  = 2.5 hours

15 km=3 hours

x km = 2 .5 hours

So by cross multiplication we get the value of x

$15=3\\x=2.5$

Hence

$3x= 15\times 2.5\\3x= 37.5$

Hence for finding the value of x put the value 3 which is with x to denominator  we get x

$x=\frac{37.5}{3} \\x=12.5$

So for covering a distance 12.5 km it takes 2 hour 30 minutes .
