Question

Two cars are moving at 30 kmph in same direction at an interval of 10 minutes. if a truck moving in the opposite direction crosses the two cars at an interval of 4 minutes the speed of the truck is​

Answer 1

Answer:

Here we will apply relative concept let the speed of the car is u then relative speed of car with respect to car c is (u+30)

Distance is 5 kilometres

Time is 4minutes= 4÷ 60 hours

Speed= distance/ time

U+30= 5/4/60

U+30=5×60/4

On solving above equation we get

U+30 = 75 then u= 75 - 30= 45 km/h
