Charge = Current/time
Q = It
t = Q/I = 15/20 = 0.75 s
Answer:
Explanation:
Call the bike on the right A
Call the bike on the left B
The car begins it's time when it passes A
4 minutes later, it passes B.
But B has moved in 4 minutes and that is the key to the problem.
How far has B moved.
t = 4 minutes = 4/60 hours = 1/15 of an hour.
d = ?
rate = 30 km / hr
d = r * t
d = 30 km/hr * 1/15 hours = 2 km
The distance between the bikes is 5 km.
So the car has traveled 5 - 2 = 3 km
d = 3 km
r = ?
t = 4 minutes = 1/15 hour
r = d/t = 3/(1/15)= 3 / 0.066666666 = 45 km/hr.
The distance is 1760 km
The speed is 960 km hour I.e 960 divide by 60 = 16 km/minute
hence in time 1 hour 50 minutes I.e 110 minutes
distance travelled is 110 - 16 = 1760 km
