Question

A car travels at 40 km/hr for the first 5 hrs & then 45 km/h for the next 6 hrs. Find the ratio of distances travelled,​

Answer 1

Answer:

20:27

Step-by-step explanation:

case 1.

Given speed = 40

Time. = 5

We know that speed = distance/time

so distance = speed*time

40*5. =. 200

case 2

Given speed= 45

Time. = 6

distance= speed* time

45* 6. = 270

200:270= 20:27

Answer 2

The ratio of distances traveled in the first and second cases is 20:27.

Given,

A car travels at 40 km/hr for the first 5 hrs

After that also 45 km/h for the next 6 hrs.

To Find,

the ratio of distances traveled.

Solution,

We can solve this using the simple following method.

To find the distance we can use the below formula,

Distance = Time×speed.

In the 1st case, the given speed = 40km/hour, and the time is 5hrs.

Here the distance covered is, 40×5=200 Kms.

In the 2nd case, the given, speed =45km/hour, and the time is 6hrs.

Here the distance covered is, 45×6=270 kms.

So the ratio is 200:270 =20:27.

Hence, the ratio of distances traveled in the first and second cases is 20:27.
