☆ Questions ☆

Distance between two places A and B is 210 km. Two cars start simultaneously from A and B in opposite direction and distance between them after 3 hour is 54 km. If speed of one car is less than that of other by 8 km per hour. Find the speed of each car.

☆ Solution ☆

☆ Given ☆

• Distance between two places A and B is 210 km. Two cars start simultaneously from A and B in opposite direction and distance between them after 3 hour is 54 km. If speed of one car is less than that of other by 8 km per hour.

☆ To find ☆

• The speed of each car.

☆ Step-by-Step-Explaination ☆

The distance between A and B is 210.

Two cars travelled simultaneously.

After 3 hours they travelled = 210 - 54 = 156

$Speed = \frac{distance \: traveled}{time \: elapsed}$

Let the speed of two cars is x.

$x + x - 8 = \frac{156}{3}$

2x - 8 = 52

2x = 60

x = 30 km/hr.

Speed of car A = 30 km/hr.

Speed of Car B = 22 km/hr.
