Walking beside you, your friend takes 50 strides per minute while you take 48 strides per minute. If you start in step, you’ll soon be out of step. When will you be in step again?
Solution 47E Step 1 : Here we need to find the time when you step again Let m be number of minutes before u step In one minute stride by you 48m Similarly in one minute strides by your friend 50(m-1) Time taken by both is 1 minute Hence we can rewrite as 50(m-1)=48m 50m -50 =48m 50m -48m = 50 2m=50 m=50/2 m=25 Therefore it takes 25 s for you to take step
