a car travels with a uniform linear speed of 36km/hr for first 2 minutes and then it travels with a speed of 15m/s for next 10 mins and finally it travels with a speed of 100 cm/min for next half an hour. calculate the total distance travelled by the car in km.

car travelled in 36 km/hr for 2 minutes
car travelled in 1 sec = 36\60*60
= 20 m in 2 sec
therefore, speed of car 15m/s for 10 mins
car travelled distance = 15*600
= 9,000m
therefore, it travelled at a speed = 100cm/min for half an hour
so, it travelled = 100*30
= 3,000 cm
hence, it total travelled a distance = 20m + 9,000m + 3,000 cm = 9.32 km
car travelled in 1 sec = 36\60*60
= 20 m in 2 sec
therefore, speed of car 15m/s for 10 mins
car travelled distance = 15*600
= 9,000m
therefore, it travelled at a speed = 100cm/min for half an hour
so, it travelled = 100*30
= 3,000 cm
hence, it total travelled a distance = 20m + 9,000m + 3,000 cm = 9.32 km
