[MOVED] finding velocity, given distance and time; etc

[martinferguson]

1) If a car moves along a perfectly straight road at a velocity of 24 m/s, how far will it go in 35 minutes?

2) If you travel southeast from one city to another city that is 314 km away, and the trip takes you 4. 0 hours, what is your average velocity?

Thank you!

Try using "d = rt" ("distance equals rate times time").

Ok - Eliz. but what I don't get is this. Using your suggest d=rt

The first problem would be d=24 m/s x 35? Or do I need to convert the minutes?

I know 24x35=840 - just not sure about converting minutes/seconds, etc.

The second problem would be 314 km = r (4.0 hrs) . . . 1256. Please advise . . .

Since the rate is given in terms of seconds, it might be wise to convert the time to "seconds".

just not sure about converting minutes/seconds, etc.

There are sixty seconds in one minute.

The second problem would be 314 km = r (4.0 hrs) . . . 1256.

What does "1256" stand for? Do you know how to solve simple linear equations of the form "2x = 4"?

Thank you.
