This requires dimensional analysis and converting units. Don't use the kinematic equations unless acceleration is constant.

ok i know that we are
 finding :distance
the points given: are speed which is 95km/h  130km   65km/h
             time=3hrs:20 minutes

anonymous · Answer

The drive home is split into two sections 1) before it rained, and 2) when it rained and the car slowed down. You have the distance during the drive before the rain, and you want the total distance of the trip. So you want to solve for the distance you traveled during the rain.

ok distance =sxtime

speed is 95km/h x 3hrs:20minutes?

anonymous · Answer

Convert 95km/h and 130km into time. You now have the time of the drive before it rained. Subtract time from the total time it took to get home (3hrs etc). You ow have time it took to drive home when it started to rain. Now multiply that time to the speed of the car traveled during the rain. You now have the distance of the car ride during the rain. Add the two distances of before and after the rain and now you have the total distance home. Then find the average speed.

Ok i got time=d/s=130km/95km/h=1.3684
                            My teacher said answer should be to the least number of significant figures so it should be 2 significant figures because of 95km/h so i got 1.4h

anonymous · Answer

Subtract the total time from the time you got
