A pump fills a pool at a rate of 20 cubic meters per hour. If each cubic meter of water is valued at \$10, how many minutes will the pump need to work to transfer \$300 worth of water?

At \$10 per cubic metre, \$300 will give you 30 cubic metres

if it takes 1 hour to pump 20 m^3
should it not take 1.5 hours, or 90 minutes to pump 30 m^3

( Wow, where do you live? Up here in Canada, 1 m^3 cost a bit more than \$1.00 )
