In this question, we have to use the intersecting chord theorem, and the formula which is

In the given circle, values of AP, CP and DP are 12m, 6m and 5m respectively .
Substituting the values in the formula, we will get

Dividing both sides by 5

that is 7X=10
= 1.42857143 or about1.42
Answer: 22.55 mph
Step-by-step explanation:
Let the speed of the train be n
4 × 62 = 248 which is the distance travelled by the car in 4 hours and the train travelled in 11 hours
11 × n = 248
11n = 248
n = 248/11
n = 22.55mph
Step-by-step explanation:
The one point where the lines intersect is one solution. If both points are on the same line it is one solution. If the lines do not intersect it is no solution.
