Answer:
1.5 minutes.
Step-by-step explanation:
The relative speed at which the car behind travels compared to the other car is 90 - 70 = 20 km/hr.
The time taken to travel 500 m ( =0.5 km) is 0.5 / 20 = 0.025 hours.
= 0.025 * 60 = 1.5 minutes.
Answer:
2 units.
Step-by-step explanation:
It is given that point M is on line segment LN. So,
(Segment addition property)
The given values are LN=3x+3, LM=4x, and MN=2x. Substitute these values in the above formula.
Subtract 3x from both sides.
Divide both sides by 3.
The value of x is 1.
Now,
Therefore, length of MN is 2 units.
