1) a bus drove 65 km/h. how far did it travel in 3 hours?
2) a bird fly at 8 m/s. how far can it travel in 10 seconds?
3) a snail can creep along at 5 cm/min. how can it travel in an hour?
4)an narrow flying at 94 m/s struck the target in 1.8 s. how far away was the target?
5) a car traveled 100 km in 2 hrs. what was the speed?
6) a boy swam 75 m in 3 min. what was the speed?
7)a bicycle traveled 60 km in 4 hrs. what was the speed?
8) a girl walked 50 km in 10 hours. what was her speed?
9) a bus traveled 369 km in 4.5 hrs. what was its speed?
Which of these problems don't you understand?
i don't understand any of them
I'll show you two. Then you can try the rest.
1) 65 * 3 = 195 km
5) 100 / 2 = 50 km/h
thank you :)
You're welcome. If you post your answers to the other problems, I'll be glad to check them for you.
To solve these problems, we need to use the formula:
Speed = Distance/Time
Let's go through each question one by one:
1) To find the distance traveled by the bus in 3 hours, we can use the formula: Distance = Speed * Time. Given that the bus drove at a speed of 65 km/h for 3 hours, the distance can be calculated as follows: Distance = 65 km/h * 3 h = 195 km.
2) For the bird flying at a speed of 8 m/s, the distance it can travel in 10 seconds can be obtained by using the formula: Distance = Speed * Time. Substituting the values, we get: Distance = 8 m/s * 10 s = 80 meters.
3) To determine how far the snail can travel in an hour, we need to convert the speed from cm/min to cm/hr. Since there are 60 minutes in an hour, we can multiply the given speed by 60 to get cm/hr. Thus, the distance traveled can be calculated as follows: Distance = Speed * Time = (5 cm/min * 60 min) = 300 cm.
4) The distance to the target can be found using the formula: Distance = Speed * Time. We are given that the narrow was flying at 94 m/s for 1.8 seconds, so the distance can be calculated as follows: Distance = 94 m/s * 1.8 s = 169.2 meters.
5) To determine the speed of the car, we can use the formula: Speed = Distance/Time. Given that the car traveled 100 km in 2 hours, the speed can be calculated as follows: Speed = 100 km / 2 h = 50 km/h.
6) For the boy swimming, we can find the speed using the formula: Speed = Distance/Time. Given that the boy swam 75 meters in 3 minutes, the speed can be calculated as follows: Speed = 75 m / 3 min = 25 m/min.
7) The speed of the bicycle can be calculated using the formula: Speed = Distance/Time. Given that the bike traveled 60 km in 4 hours, the speed can be calculated as follows: Speed = 60 km / 4 h = 15 km/h.
8) The girl's speed can be calculated using the formula: Speed = Distance/Time. Given that she walked 50 km in 10 hours, the speed can be calculated as follows: Speed = 50 km / 10 h = 5 km/h.
9) To find the speed of the bus, we can use the formula: Speed = Distance/Time. Given that the bus traveled 369 km in 4.5 hours, the speed can be calculated as follows: Speed = 369 km / 4.5 h = 82 km/h.
By using the formula Speed = Distance/Time, we can easily find the speed or distance traveled in various scenarios.
