Kayak Race

Question

In a kayak race, the participants must paddle a kayak 450 meters down a river & then return 450 meters up the river to the starting point. Susan has correctly deduced that the total time t(in sec) depends on the speed c(in m per sec) of the eater according to the following formula. Please fill in the chart.

 

 

Formula: t=450/v+c + 450/v-c

Time(t)sec    v(m/sec)   c(m/sec)

240               ?               1

300               ?               2

?                   4               3
