Question

A car traveling at a speed of 140 kmph covers 420 km. How much time will it take to cover 280 km?

Answer 1

hey mate here is your answer

speed=distance/time

140=280/time

time=2hrs

Answer 2

Answer: 2 Hours

Step-by-step explanation:

Given,

• A car travels at the speed of 140 kmph.
• It covered a total distance of 420 kms.

To Find: The time taken by the car to travel 280 kms at that constant average velocity of 140 kmph.

Explanation:

• To solve this question we need to know about the basic relationship between Distance, Average Velocity and Time.
• Basic relationship between Distance, Average Velocity and Time.(Distance/Time) = Average Velocity
• Here, we will have to calculate the Time taken by the car to travel 280 kms at that constant average velocity of 140 kmph.
• we will use the unitary method here, i.e.,
• Since the average velocity of the car is 140 kmph,

        It means that, the car can travel 140 kms in 1 hour.

        Then, the car can travel 1 km in (1/140) hours.

        Hence, it can travel 280 kms in $(\frac{1}{140}*280)=\frac{280}{140}=2$

• That is, the car takes 2 hours to travel 280 kms.

If a bus travels 126 km in 3 hours and a train travels 315 km in 5 hours, then the ratio of their speeds is ?
