If you give us the situation described then I'll be able to help.
Given :
A race car moves along a circular track of radius 100m at a velocity of 25m/s.
To Find :
(a) What is the time taken to complete one lap of the circular track.
(b) What is the time taken for 10 laps.
Solution :
Circumference of circular track,

a) Time taken to complete one lap is :

b) Time taken to complete 10 laps is :

Hence, this is the required solution.
Current = power/voltage = 1200w/120v = 10 amperes. Constantly. Whenever the heater is turned on and heating.
