Question

Kalay wants to rent a kayak rentals cost 14.50 for a hour kalay rents for a hour in 45 mins how much will it cost him

Answer 1

Just set up the equation to solve:
x = 105 min (1hr 45min - hard to read your question so I assume this)
14.50=60 min
x/14.50=105/60...solve for x
x=1.75*14.50
x=23.375
So for 1hr 45 min, Kalay would pay $23.38

Answer 2

It will cost $652.50.
