You have a rate of 3.57 meters per second. The time is measured in tenths of a second. So, change the rate into meters per tenth of a second. $$\frac{ 3.57m }{ 1s }$$

So, if she jumps 3.57 meters in one second, how many meters does she jump in a tenth of that time? You have to divide the meters by the same amount you divided the seconds.
