Let speed of the car = 448/8 = 56 km/hr
Then, speed of the bike = 56 * 100/140 = 40 km/hr
Therefore, sum of the time taken by the car and bike together = 280/56 + 120/40 = 5 + 3 = 8 hours

A car covers 448 km in 8 hours and the speed of the car is equal to 1...
To solve this problem, we can break it down into two parts: finding the speed of the car and bike, and then using that information to calculate the time taken by each to cover the given distances.

Step 1: Finding the speed of the car and bike
Given that the car covers 448 km in 8 hours, we can calculate its speed by dividing the distance by time:
Speed of car = Distance / Time = 448 km / 8 hours = 56 km/h

Since the car's speed is equal to 140% of the bike's speed, we can use this information to find the speed of the bike:
Speed of bike = (Speed of car) / 1.4 = 56 km/h / 1.4 = 40 km/h

Step 2: Calculating the time taken by the car and bike
Now that we have the speeds of the car and bike, we can calculate the time taken by each to cover the given distances.

Time taken by the car to cover 280 km:
Time = Distance / Speed = 280 km / 56 km/h = 5 hours

Time taken by the bike to cover 120 km:
Time = Distance / Speed = 120 km / 40 km/h = 3 hours

Step 3: Finding the sum of the times taken by the car and bike
To find the sum of the times taken by the car and bike, we add the individual times together:
Total time = Time taken by car + Time taken by bike = 5 hours + 3 hours = 8 hours

Therefore, the sum of the time taken by the car to cover 280 km and the time taken by the bike to cover 120 km is 8 hours. Hence, option (c) is the correct answer.
