Seattle Kayaking Club
can you help please?
1. Tim paddles his kayak 12 km upstream against a 3 km/h current and back again in 5 hours and 20 minutes. In that time, how far could he have paddled in still water?
2)Members of the Ski Club contributed equally to obtain $1800 for a holiday trip. When 6 members found they could not go, their contributions were refunded and each remaining member then had to pay and additional $10 to remain at their goal of $1800. How many went on the trip?
3) When Ace Airlines changed to planes that flew 100 km/h faster than its old ones, the time of its 2800 km Dallas-Seattle flight was reduced by 30 minutes. Find the speed of the new planes.
Can you please also show me how to do this?
Thank you for your help
