If the velocity of a bicycle is 10m/s .how long will it take to cover a distance of 18km

Explanation: 18 / 3.6 = 5m
(use velocity = distance / time)
v = d/t
10 = 5/t
10t = 5 (divide 5 by 10 to isolate time)
t = 0.5s

Hope this helps :)

Btw Ik the answer sounds completely illogical but this is a pretty unrealistic situation.

The radiation of the fire causes the saucepan to heat up. the conduction of the saucepan then to distribute the heat over the saucepan and to give heat to the water. the convection of the water distributing the heat within the water, till all the water is boiling
