could you see if my answers are correct?? if not could you please help me get them right? thanks very much
A train leaves a station at noon. train is 180 miles from its destination at 12:45 pm and 90 miles from its destination at 2:15.
how far is station from destination?225 miles
S = D/T = 90miles/90 min = 1 mile per min or 60 mph
note: got 3 3/4 hrs( noon to 3:45 pm)
D = TS = 3 3/4 hrs(60mph) = 225 miles from station to destination
at what time will the train reach the destination? 3:45 pm
t=d/s = 90 miles/60mph = 1 1/2 hrs
2:15 pm + 1:30 = 3:45 pm
Both answers are correct!
You live 2 3/ 4 miles from school. In the morning, you walk 1/ 3 mile directly toward school to the bus stop. Later, when you get off the bus, you walk home from there. How many miles do you ride to and from school each day?
To find the correct answers for the given questions, let's go through them step by step:
1. How far is the station from the destination?
Based on the given information, we know that the train is 180 miles from its destination at 12:45 pm and 90 miles from its destination at 2:15 pm. The time between 12:45 pm and 2:15 pm is 1 hour and 30 minutes.
To get the distance between the station and the destination, we can calculate the difference between the distances at the two given times:
Distance at 2:15 pm - Distance at 12:45 pm = 90 miles - 180 miles = -90 miles
However, a negative distance doesn't make sense in this context, so it seems there might be an error. Let's correct this calculation:
Distance from the station to the destination = 180 miles + 90 miles = 270 miles
Therefore, the correct answer is that the station is 270 miles from the destination.
2. At what time will the train reach the destination?
To calculate the time it will take for the train to reach the destination, we can divide the distance by the speed:
Time = Distance / Speed
From the previous answer, we know that the distance from the station to the destination is 270 miles. However, we need the speed of the train to calculate the time accurately. The speed is not provided in the given information, so we cannot determine the exact time.
If the speed of the train is given in the question, you can divide the distance by the speed to get the time.
Once we have the speed, we can calculate the time by:
Time = 270 miles / Speed
Without the speed, we cannot determine the exact time the train will reach the destination.
