This post is a part of Project IR Butler 2019-20. Click here for Details


A portion of an automobile test track is divided into Segment A, Segment B, and Segment C, in that order. In a performance test on a car, the car traveled Segment A at a constant speed of 140 kilometers per hour (km/h). Immediately after this, the car rapidly slowed on Segment B and then traveled on Segment C at a constant speed of 70 km/h. The length of Segment C is 3 times the length of Segment A, and it took a total of 42 minutes for the car to travel both segments A and C. In the table, select the length of Segment A, in kilometers, and select the length of Segment C, in kilometers. Make only two selections, one in each column.

Let length of segment A=x
So length of segment C=3x

And total time taken is 42 min =42/60 hours= 0.7 hours

So we will use Total time= distance in A/Speed in A + distance in C/Speed in C

0.7= x/140 + 3x/70
0.7*140= x+6x
.7*140=7x
x=14

So length of segment A=14
Length of segment C=42

Speed in Segment A = 140km,
Speed in Segment B = unknown
Speed in Segment C = 70km.

Length of segment A = x,
Length of segment C = 3x.

total time taken to cover Segment A & B = 42/60 = 0.7 hrs.

The equation which will be formed is: x/140 + 3x/70 = 7x/140 = 7/10.

=> x = 14 km, 3x = 42 km


Answer : Segment A: 14 km, Segment B = 42 km.
