Question

0. A car, running at 45 km/hr takes 6 hours to cover a journey. At what speed must it travel complete the journey in 5 hours? 1. A car covers a certain distance in 50 minutes if it runs at 45 km per hour,​

Answer 1

Answer:

37.5 Km/hour

Step-by-step explanation:

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

car running at speed = 45 Km /h r

Time= 6 hours

We need to find the  speed at which  it travel to complete the journey in 5 hours

Let us assume  x= speed for 5 hours

Now for solving this make  the equation as follows

45km/hours =6 hours

x= 5 hours

Now by simple cross multiplication we get the value of x which is nothing but the speed for covering in 5 hours

$6x= 45\times 5\\6x= 225\\x=\frac{225}{6}$

Now finding the lowest term  by solving the fraction

$=\frac{112.5}{3}$

(As both are divisible by 2)

Again Finding the  lowest term

$=\frac{37.5}{1} \\=37.5$

( As both are divisible by 3)

So it conclude that it travelled  at a speed of 37.5 km /hours to cover a distance for 5 hours.

1. Car covers distance  in 50minutes

   Speed = 45 km /hour  

Answer 2

PROVIDED INFORMATION :-

A car, running at 45 km/hr takes 6 hours to cover a journey

A car covers a certain distance in 50 minutes if it runs at 45

QUESTION:-

1. A car, running at 45 km/hr takes 6 hours to cover a journey. At what speed must it travel complete the journey in 5 hours?

2. A car covers a certain distance in 50 minutes if it runs at 45 km/hr. How much time will it take to cover the same distance at a speed of 30km/hr?

TO FIND :-

At what speed must it travel complete the journey in 5 hours = ?

How much time will it take to cover the same distance at a speed of 30km/hr = ?

SOLUTION :-

in these question we have provided two

question

first solution :-

Given that the speed of car = 45 km/hr

Time = 6 hour

Distance Speed × Time

= 45 x 6

= 270 km

Now, time = 5 hours

Distance = 270 km

New Speed = Distance / Time

= 270 /5 km

= 54 km/hr

SECOND SOLUTION :-

given 50 /60 hour. V1 = 45 km/hr

Find time for same distance

d = 50 /60 × 45 = 37.5

time = 37.5 / 30 = 1.25

hence , the answer is 1.25
