At the rate of y yards per m minutes, how many yards does a swimmer travel in x hours?
A. ymx
B. yxm
C. 60ymx
D. 60ymx
E. 60xym
We can write this in W = RT formula
let work be Y and T be m minutes then rate (R) = Y/m.
Now question asks us to find the answer in terms of Y in x hours of time.
As per our analysis , Y = RT, we got R from above
now sub R value in above equation then Y = ( Y/m) T
We have m in minutes and T as in hours then convert this into minutes T = 60x
=> Y(60x) / m.
