Answer» Step-by-step explanation: ROHAN participated in a RACE . He need to cover the DISTANCE of 560 m in the race. In each step, he COVERED 0.5 m . After covering 347 m he fell. How many steps were left to complete the race ? ANSWER Now given total distance to be covered will be 560 m. He covered 0.5 m from each step. So in 1 m he covers 1/0.5 = 2 steps. Now total steps remaining will be 560 – 347 = 213 m So 213 x 2 = 426 steps

ROHAN participated in a RACE . He need to cover the DISTANCE of 560 m in the race. In each step, he COVERED 0.5 m . After covering 347 m he fell. How many steps were left to complete the race ?

ANSWER

Now given total distance to be covered will be 560 m.

He covered 0.5 m from each step.

So in 1 m he covers 1/0.5 = 2 steps.

Now total steps remaining will be 560 – 347 = 213 m
