The number of calories burned while jogging varies directly with the number of minutes spent jogging. If George burns 180 calories by jogginh for 25 minutes, how many calories does he burn by jogging for 40 minutes?

Shaun is developing a weight loss regimen, which includes both a workout plan and a calorie-restriction plan. Shaun wants to work out for no less than 30 minutes and no more than 60 minutes a day and consume no less than 2,000 and no more than 2,500 calories. If each minute, m, of his workout time burns 50 calories .which of the following inequalities represents the number of minutes,m, that that Shaun can work out each day to burn off as many calories as he consumes?

When amy exercise in her fitness certer for 1 hour she burns a total of 475 calories. If she burns 9 calories a minute jogging on the treadmilll and then burns 6.5 calories a minute pedalling on the stationary bicycle, how many minutes of the hour does she spend exercising on the bicycle?

The above bar graph shows the number of calories burned per minute for three types of exercise , assuming that the exercise is performed vigorously. Jackie spent an hour exercising vigorously . She spent twice as much time doing aerobics as she did walking, and 1 1/2 times as much time swimming as she did aerobics . According to the graph, how many calories did Jackie expect to burn during that hour of exercise ?

The time represented by the clock hands of a pendulum clock depends on the number of oscillations performed by pendulum. Every time it reaches to its exterme position the second hand of the clock advances by one second that means second hand moves by two second when one oscillation is completed. (a) How many number of oscillations completed by pendulum of clock in 15 minutes at calibrated temperature 20^(@)C (b) How many number of oscillations are completed by a pendulum of clock in 15 minutes at temperature of 40^(@)C if alpha = 2 xx 10^(-5)//"^(@)C (c ) What time is represented by the pendulum clock at 40^(@)C after 15 minutes if the initial time shown by the clock is 12:00 pm? (d) If the clock gains two seconds in 15 minutes in correct clock then find-(i) Number of extra oscillations (ii) New time period (iii) change in temperature.
