Two automobiles are 155km apart and travelling toward each other one automobile is moving with velocity of 70 km/hr and the other with 32 km/hr In how many hours will they meet?
155/(70+32) = 155/102 ≈ 1.52 hours
70T+32T = 155
T = 152 hrs.
To find out how many hours it will take for the two automobiles to meet, we need to use the formula:
Time = Distance / Relative Velocity
First, we need to calculate the relative velocity of the two automobiles. Relative velocity is the combined velocity of the two objects in the same direction, taking into account their individual velocities. In this case, the automobiles are approaching each other, so we can simply add their velocities:
Relative Velocity = Velocity of Automobile 1 + Velocity of Automobile 2
Relative Velocity = 70 km/hr + 32 km/hr
Relative Velocity = 102 km/hr
Now we can calculate the time it will take for the two automobiles to meet:
Time = Distance / Relative Velocity
Time = 155 km / 102 km/hr
Time ≈ 1.52 hours
Therefore, it will take approximately 1.52 hours for the two automobiles to meet.
