A bus travelling at 99 km/h completes a journey in 14 hours. At what speed will it have to cover the same distance in 18 hours?
77 km/h
To solve the problem of determining the speed at which a bus must travel to complete the same distance in 18 hours, we can follow these steps:
Step 1: Determine the total distance.
We know the initial speed of the bus is 99 km/h and it completes the journey in 14 hours. Thus, we can calculate the total distance using the formula:
Distance = Speed × Time
Distance = 99 km/h × 14 h = 1386 km
Step 2: Calculate the required speed for 18 hours.
To find the speed required to cover the same distance in 18 hours, we can rearrange the distance formula:
Speed = Distance ÷ Time
Speed = 1386 km ÷ 18 h ≈ 77 km/h
Conclusion:
The bus must travel at approximately 77 km/h to complete the journey in 18 hours. Therefore, the correct answer is 77 km/h.
