Question

11. A car travelling at a speed of 60 km/h left the place P and an hour later another car leaves the place P and catches up with the first car after travelling 4 hours at a uniform speed. What was the average speed of the car?​

Answer 1

Answer:

75 km/hr

Step-by-step explanation:

as the another car B started 1 hr late and catches after 4 hrs travel by car A hence total travel by car A =4+1 =5 hrs.

hence total distance cover by car A=60km/hr*5hr=300km

hence to cover distance of 300 km in 4 hrs the speed of car B should be =300/4 =75km/Hr
