Question : A bus covers a 60-kilometre distance in 1 hour 30 minutes, whereas the same distance is covered by a car in 45 minutes. What is the ratio of the speed of the car to the speed of the bus?

Option 1: 5 : 3

Option 2: 3 : 5

Option 3: 1 : 2

Option 4: 2 : 1

Question : The speeds of A and B are in the ratio 3 : 5. A takes 30 minutes more than B to reach the destination. In how much time does A reach the destination?

Option 2: 1 hour 10 minutes

Option 3: 1 hour

Option 4: 1 hour 5 minutes

Question : A car can cover a certain distance in $4\frac{1}{2}$ hours. If the speed increases by 5 km/hr, it would take $\frac{1}{2}$ hour less to cover the same distance. Find the slower speed of the car.

Option 1: 50 km/hr

Option 2: 40 km/hr

Option 3: 45 km/hr

Option 4: 60 km/hr

Question : A bus moving at 40 km/hr covers a distance in 6 hours 15 minutes. If it travels the same distance at 50 km/hr, how long will it take to cover the distance?

Option 1: 2 hours

Option 2: 6 hours

Option 3: 4 hours

Option 4: 5 hours

Question : A car, during its entire journey of 5 hours, travels the first 45 minutes at a certain speed, the next 75 minutes at a speed of 85 km/hr, and the last 3 hours at a speed of 70 km/hr. During its entire journey, the average speed of the car is found to be 73 km/hr. What is the speed (in km/hr) of the car during the first 45 minutes?

Option 1: 65

Option 2: 68

Option 3: 62

Option 4: 72
