Question

A bus leaves a station at 1 P.M., traveling west at an average
rate of 44 mi/h. One hour later a second bus leaves the same station, traveling
east at a rate of 48 mi/h. At what time will the two buses be 274 mi apart?

Im not good with these just asking for some assistance on how to figure it out. thanks in advnace

Answer 1

3.5 hours

Distance = Rate * Time
Once the second bus goes...they are driving apart at a rate of 92 MPH.
Also, consider that the first bus already went 44 miles before the second bus left.

274 - 44 = 230

230 / 92 = 2.5 hours

Then add the hour the first bus was traveling.

Total is 3.5 hours
