Heather and Matthew walk eastward with a speed of 0.98 m/s. If it takes them 34 min to walk to the store, how far have they walked?

If Joe rides south on his bicycle in a straight line for 15 min with an average speed of 12.5 km/h, how far has he ridden?

It takes you 9.5 min to walk with an average velocity of 1.2 m/s to the north from the bus stop to the museum entrance. What is your displacement?

How would I solve these problems?

Ok, their velocity is .98m/s due east. The time required is 34min, so how many seconds are there in 34min? 34min * 60sec/min
Use d=v*t where v=.98m/s and the t you calculated above.

If Joe rides for 15min then that is what part of an hour? 15min*1hr/60min= ?
Now use d=v*t =12.5km/hr * the time you just calculated.

If it takes 9.5min how many seconds is that? 9.5min * 60sec/1min = ?
Now use d=v*t = 12.m/s * the time you calculated.

One of the main lessons with these problems is to make sure that your units match. Hours, minutes and seconds are units of time, but the units must match when doing calculations.

3.125 km

To solve these problems, follow these steps:

For the first problem:
1. Convert the time from minutes to seconds: 34 minutes * 60 seconds/1 minute = 2040 seconds.
2. Use the formula d = v * t, where v is the velocity of 0.98 m/s and t is the time of 2040 seconds, to calculate the distance walked: d = 0.98 m/s * 2040 seconds = 1999.2 meters.

For the second problem:
1. Convert the time from minutes to hours: 15 minutes * 1 hour/60 minutes = 0.25 hours.
2. Use the formula d = v * t, where v is the average speed of 12.5 km/h and t is the time of 0.25 hours, to calculate the distance ridden: d = 12.5 km/h * 0.25 hours = 3.125 kilometers.

For the third problem:
1. Convert the time from minutes to seconds: 9.5 minutes * 60 seconds/1 minute = 570 seconds.
2. Use the formula d = v * t, where v is the average velocity of 1.2 m/s and t is the time of 570 seconds, to calculate the displacement: d = 1.2 m/s * 570 seconds = 684 meters.

Remember to double-check your units and show your work when reposting.

To solve these problems, follow these steps:

1. Convert the given time into seconds:
- For the first problem, 34 minutes is equal to 34 * 60 = 2040 seconds.
- For the second problem, 15 minutes is equal to 15 * 60 = 900 seconds.
- For the third problem, 9.5 minutes is equal to 9.5 * 60 = 570 seconds.

2. Use the formula d = v * t, where d is the distance, v is the velocity, and t is the time (in seconds for consistency).

- For the first problem, the velocity is 0.98 m/s, and the time is 2040 seconds. So, d = 0.98 * 2040 = 1999.2 meters.
- For the second problem, the velocity is 12.5 km/h, which needs to be converted to m/s. 1 km = 1000 m and 1 hour = 3600 seconds, so 12.5 km/h = 12.5 * 1000 / 3600 = 3.4722 m/s. The time is 900 seconds. So, d = 3.4722 * 900 = 3124.98 meters (approximately).
- For the third problem, the velocity is 1.2 m/s, and the time is 570 seconds. So, d = 1.2 * 570 = 684 meters.

Remember to always check for unit consistency and convert if necessary.
