You haven't said whether the two resistors are connected
in series or in parallel. It makes a difference.
-- If they are in series, then their combined effective resistance is
(3 + 2) = 5 ohms.
Current in the circuit is (voltage)/(resistance) = 1.5/5 = 0.3 Amp.
-- If they are in parallel, then their combined effective resistance is
(3 x 2) / (3 + 2) = (6/5) = 1.2 ohms.
Current in the circuit is (voltage)/(resistance) = 1.5/1.2 = 1.25 Amp.

Average speed of the driver is given as

if he moved for total time t = 3.5 hours
so the distance between the tow is given as



so the distance between St. Louis and Chicago is 224 miles
Answer:
Explanation:
Given
length of window 
time Frame for which rock can be seen is 
Suppose h is height above which rock is dropped
Time taken to cover 
so using equation of motion

where y=displacement
u=initial velocity
a=acceleration
t=time
time taken to travel h is

Subtract 1 and 2 we get


and from equation 
so 

and 
so 



substitute the value of
in equation 2
