Let suppose Length(L)<span>= 2 1/4 units which is 9/4 in proper fraction and 2.25 in decimal</span> let suppose Width(W)= 7/10 units which is 0.7 in decimal Perimeter(P)=? Now, we should use the formula P = 2(L+B) = 2(2.25+0.7) = 2(2.95) = 5.9 so, the perimeter = 5.9 units.
A man travels 600km partly by train and partly by car. If he covers 400km by train and the rest by car, it takes him 6 hours and 30 minutes. But if he travels 200 km by train and rest by car, he takes half an hour longer.find the speed of the train and that of the car
