It is given to us that Tatenda takes t seconds to mow a square meter of lawn and Ciara takes c seconds to mow a square meter of lawn.
It is also given to us that Tatenda mows 700 square meters of lawn per week and Ciara mows 750 square meters of lawn per week.
Thus, if Tatenda mows 700 in a week, then that means he took
seconds to complete the mowing.
Likewise, if Ciara mows 750 in a week, then that means she took
seconds to complete the mowing.
