alleryଗୋଟିଏ ଟ୍ରେନର ଗତିବେଗ ନିର୍ଣ୍ଣୟ କରନ୍ତୁ। I: ଏହା 120 km ଅତିକ୍ରମ କରେ। II: ଏହା 2 ଘଣ୍ଟା ସମୟ ନିଏ।
Aଏକତ୍ର ହେଲେ ମଧ୍ୟ କୌଣସିଟି ଯଥେଷ୍ଟ ନୁହେଁ
Bଉଭୟ ଏକତ୍ର ଆବଶ୍ୟକ
Cକେବଳ I ଯଥେଷ୍ଟ
Dକେବଳ II ଯଥେଷ୍ଟ
Answer & Solution
Correct answer: B. ଉଭୟ ଏକତ୍ର ଆବଶ୍ୟକ
ଗତିବେଗ ହେଉଛି ଦୂରତା ହରଣ ସମୟ, ତେଣୁ 2 ଘଣ୍ଟାରେ 120 km ପାଇଁ ଉଭୟ ଆବଶ୍ୟକ, ଯାହା 60 km/h ପ୍ରଦାନ କରେ।
