1. A fish with a mass of 3 kg causes a fishing pole to bend 9 cm. If the amount of bending varies directly as the
mass, by how much will the pole bend for a 2kg fish?
2. If it takes 4 hours to cover a certain distance at 40 kph. How long would it take to cover it at 50 kph?
3. If z varies directly as x and inversely as y, and if z is 5 when x = 2 and y = 3, find z when x = 5 and y = 3
4. c varies jointly as a and b.tfc 90 when a = 30 and b = 28, find c when a = 42 and b = 16.
5. If a varies inversely as b with the constant of variation k = %, what is a when b = 5?
