Therefore, x=2 and y=-1. that is (2,-1).
A : 5.-2 + 5 ≠9 not solution
B : 5.1 + 4 = 9 so 3.1 + 2.4 = 11 ≠4 not solution
C: 5.2 + = 9 so 3.2 + 2.-1 = 4 both are right then C is solution
D: 5.4 - 4 = 16 ≠ 9 not solution
speed of the car have to be to complete the trip in 17 hours?
Answers
The speed of car must be 60mile/hour, so that the trip will complete in 17 hours.
What is speed?
The rate of change of position of an object in any direction is called speed.
How do you calculate speed when distance and time is given?
According to the given question
At a speed of 68 miles per hour, the trip will be complete in 15 hours.
⇒ Total distance covered in 15 hours = 68 × 15 = 1,020 miles
( because, distance = speed × time)
Therefore, the speed of car to complete the trip in 17 hours
=
Hence, the speed of car must be 60mile/hour, so that the trip will complete in 17 hours.
