(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1. A person takes a trip, driving with a constant speed of 89.5 km/h, except for a 22 min rest stop. If the person's average speed is 77.8 km/h, how much time is spent on the trip and how far does the person travel?

2. Two sprinters finish with times of 3:53.58 and 3:55.66. Assuming that both run 1609 m at constant velocity,, what distance separates them at the end of the race?

2. Relevant equations

S = d/t?

I don't know but I sorta feel they're the ones involve here. PLease help me, cause I don't have any idea with this, and its our exam tomorrow

3. The attempt at a solution

1. I did a tabular there.

1st Part has only speed given.

2nd Part has only the time. [rest for a moment]

3rd Part has the total speed.

but got stuck when solving it, cause I can't find the distance and time of the 1st velocity. I tried diving the time of the 2nd to the speed of the first but it doesn't seem to work out.

2. For here so far

i just converted the two times into seconds and then I each multiplied them to their designated speeds but got stuck in what i really need to find.

Sorry :( i really need your help, can you please please please help me :(((

i'm sorry if this is all i can give for an attempt. :'(
