You have to use the formula :
time (in hours) x speed (in km/h) = distance (in km)
to solve your question
Since you are looking for time, you will have to solve for it :
time = distance / speed
you might also wish to get a result in Minutes, not in fractions of an hour, which is awkward to work with:
time = (distance / speed) x 60
You don't have to use brackets, but it makes it easier to understand.
time (min) = 78 / 100 x 60
46.8 minutes or 48 minutes and 48 seconds
It takes7 minutes and 7 secondsto drive 4km at 100km/ph
54 minutes
one hour, 35 minutes, 24 seconds
34 minutes and 48 seconds Approx. 35 minutes
1 hour and 34 minutes
Time = Distance/Speed = 85/100 = 0.85 hours.
If you are driving 100km, it's equal to 62.1371 miles. It would take approximately 31 minutes to drive at a speed of 120 mph.
Time = Distance/Speed = 100/75 = 11/3 hours = 1 hour 20 minutes.
depends on how fast can you drive.:)
Four and a half hours, assuming a constant speed.
Depend entirely on the amount of power and friction.
