The admission for a concert starts at 6 pm and closes at 7 pm. There are 900 people attending and they arrive at a constant rate.
How many minutes will the concert last?
Find the flow of people per minute.
A cyclist travels 70 \text{ m} every 10 seconds.
How many lots of 10 seconds are in 1 minute?
Hence find the speed of the cyclist in metres per minute.
How many metres will the cyclist travel in one hour?
Hence find the speed of the cyclist in kilometres per hour.
A worm takes 15 \text{ sec} to travel 20 \text{ cm}.
How many lots of 20 \text{ cm} are there in 1 \text{ m}?
How long does it take for the worm to travel 1 \text{ m}?
Hence, state the rate of the worm's time taken per distance travelled in \text{sec/m}.
If 9600 \text{ L} of water flows through a tap in 8 hours, calculate the tap's flow rate per minute.
Convert the following as indicated:
600 \text{ km/hr} to \text{km/min}
300 \text{ mL/hr} to \text{mL/min}
36 \text{ dollars/hr} to \text{dollars/min}
96 \text{ L/day} to \text{L/h}
36 \degree \text{/s} to \degree \text{/min}
21 \text{ m/min} to \text{m/s}
A bike travels 83 \text{ m} in 12 seconds.
How many lots of 12 seconds are there in 1 minute?
Find the speed of the bike in \text{m/min}.
Mae ran for 4 hours at the speed of 4 \text{ km/h}.
Express Mae's speed in \text{m/h}.
Hence, state the total distance Mae travelled in metres.
A crabeater seal can filter 0.9 \text{ L} of water in each dive while looking for food during a 30 minute time period.
State the rate of water filtered in:
\text{L/min}
\text{L/h}
\text{mL/min}
\text{mL/s}
Peter runs daily and usually covers his 19 \text{ km} in 75 \text{ min}. He also enters half marathon and full marathon events. The last time he ran the Sydney half marathon it took him 126 \text{ min} to complete the 21 \text{ km} event.
State his running rate during his daily run in \text{km/h}.
State his running rate during the half marathon in \text{km/h}.
In which event was he running faster on average? On his daily run or in the half marathon?
A runner approximates the distance between two street lights to be 33 \text{ m}. It takes him 10 \text{ sec} to run from one street light to the other.
State the runner's speed in:
\text{m/sec}
\text{m/min}
\text{m/h}
\text{km/h}
A cyclist approximates the distance between two trees as 39 \text{ m}. She counts 30 heart beats as she cycles from one tree to the other. The cyclist's smart watch says that her heart is beating at 90 \text{ bpm}.
How many seconds does it take the cyclist to get from one tree to the other?
State the cyclist's speed in:
\text{m/s}
\text{m/min}
\text{m/h}
\text{km/h}
A baby is weighed on their first birthday and found that they've gained 5.475 \text{ kg} since they were born. Assuming there are 365 days in a year, state the rate of growth, correct to three decimal places in:
Kilograms / day
Grams / day
Grams / hour
The Earth completes one full rotation in a day. As it rotates, a particular point on the Earth moves 18\,900 \text{ km} in 12 hours.
State the speed of the point on the Earth in:
Kilometres / day
\text{km/h}
\text{m/h}
\text{m/s}
Order these trips in ascending order of average speed:
A Driving 180 \text{ km} in 3 hours
B Bicycling 132 \text{ km} in 4 hours
C A taxi trip that took 15 minutes to travel 11 \text{ km}
