Hey. Got a Question for you.

A car drives with an average speed of 80km/h for 5km. The first half it drives at 95km/h. How fast did it drive for the second half of the distance?

Time taken?

80 kms = 60mins
5 kms =?

5 kms = (5 * 60) / 80
5 kms = 3.75 minutes.

First half :-

95 kms = 60mins
2.5 kms =??

2.5kms = (2.5*60) / 95
2.5kms =1.5789 minutes

2nd half = 3.75 - 1.5789 = 2.1711

2.1711 minutes = 2.5 kms
60 minutes =??

( 60 *2.5) /2.1711
= 69.089

answer = 69.089 kms/hour.
