13:33 at the starting of the video u said when time is constant Distance will be directly prop to speed , C,B value should change it to B,C only , why did u write same C,B value
Pls check ... Initially I said the same ...If time is constant, distance is directly proportional to speed,which means if distance ratio is A:B , then speed ratio is also A:B In Direct proportion, ratio should be same order

Hai mam. In the 4 th sum , why u didn't convert minutes into hours. ????
Workout sum = 49 mins
49 min w1
WORKOUT 2:
Car's speed = Distance/Time= 540 km/9 hrs = 60 km/hr.
Train's speed = 2 x Car's speed -------> Train's speed = 2 x 60 km/hr = 120 km/hr.
Bike's speed = 2/3 x Train's speed ----> Bike's speed = 2/3 x 120 km/hr= 80 km/hr.
Distance traveled by Bike's in 5 hrs ----> 80 km/hr x 5 hrs = 400 km.

10 th question tamil translation will be wrong....😘

Pls check ... Initially I said the same ...If time is constant, distance is directly proportional to speed,which means if distance ratio is A:B , then speed ratio is also A:B
In Direct proportion, ratio should be same order
4:05 don't show ad poster while teaching it is hiding the content, either post it at the beginning or end of the video
Car average speed=540/9=60km/hr
