Given

Speed = 5.9 miles / hour

1 mile = 1.609 km

1 hour = 60 min

Time given = 98 min

Convert miles to km, hours to min and calculate the distance for 98 min:

3. Explain the relationship between power, energy and time.

likoan [24]

There is a very simple relationship between the three. First off, power is the amount of energy used over a certain amount of time. Energy is the capacity of carrying out that power. Lastly, time depends on how much energy you have to exert the work.

Hope this helps :)
