Answer» I don't know the answer because it's of class 11 but I am of class 9th so please try again with some another Hii can you help me in grammer speed = 126x5/18 = 35 m/stime =distance/speed time = 245/35 = 7 second speed=126x5/18=35m/stime=distance/speedtime=245/35=7 second Given is the data of the speed and the distance travelled by car, and we need to find out the time taken to travel the given distance with the given speed. Therefore, we will apply the equation of motion. Given is the u= 126/frac {km} {h}, convert it into m/s which will be 35/frac {m} {s}. Given that d = 245m. d=(u+/frac{v} {2} ) /times t.t = 14 second it question answer 7second |
