A car has taken three and a quarter hours to make the Madrid-Zaragoza route at an average speed of 100 km/h. How long will a bus take at an average of 90 km/h?
To find out how long the bus will take, we need to use the equation:
Time = Distance / Speed
The distance between Madrid and Zaragoza remains the same for both the car and the bus. Let's assume it is D km.
For the car:
Time(car) = D / 100 km/h = 3.25 hours
For the bus:
Time(bus) = D / 90 km/h
Since the distance is the same, we can equate the two expressions for time:
3.25 = D / 100
D = 3.25 * 100 = 325 km
Now we can find the time it will take for the bus:
Time(bus) = D / 90 km/h = 325 / 90 ≈ 3.61 hours
Therefore, the bus will take approximately 3.61 hours to make the Madrid-Zaragoza route at an average speed of 90 km/h.
To find out how long the bus will take to make the Madrid-Zaragoza route at an average speed of 90 km/h, we can use the formula:
Time = Distance / Speed
Given that the car took 3.25 hours to complete the route at an average speed of 100 km/h, we need to determine the distance traveled.
Distance = Speed x Time
Distance = 100 km/h x 3.25 hours
Distance = 325 km
Now, to find out how long the bus will take, we can substitute the values into the formula:
Time = Distance / Speed
Time = 325 km / 90 km/h
Time = 3.61 hours
Therefore, the bus will take approximately 3.61 hours or 3 hours and 36 minutes to make the Madrid-Zaragoza route at an average speed of 90 km/h.
