Mandy is driving north of 50km/he. If his sister is driving another car at a velocity of -25km/hr, in what direction is she driving?
62.5 miles
99.167 miles.
90 min is an hour-and-a-half. One-and-a-half times 50 is 75 miles.
The answer is average speed.It's average speed because say for example you know your car is traveling 30 km in 20 minutes, you'd have to divide the total distance traveled by the total time.
If you mean the average speed, simply divide the total distance by the total time.
Average speed = distance/time
60 m
5400 Miles
99.167 miles.
120 minutes = 2 hours2 hours x 50 mph = 100 miles.
75 minutes = 60 minutes + 15 minutes = 1.25 hours 60 x 1.25 = 75 miles =============================> 75 miles.
50 mph = 50 miles per 60 minutes = 50*105/60 miles in 105 minutes = 87.5 miles.
90 min is an hour-and-a-half. One-and-a-half times 50 is 75 miles.
distance = speed x time 75 mins = 75 ÷ 60 hours = 1.25 hours distance = 70 mph x 1.25 hrs = 87.5 miles
(75 divide by 60 ) x 40 mph = Traveled So it works out to : 1.25 x 40 = 50 Miles Traveled
It is a total distance of about 100 miles and a traveling time of about 1 hour and 50 minutes.
Distance = Average speed * Time = 55 mph * 0.5 hour = 22.5 miles.
Distance covered in nth second means the distance covered in that particular second . It cannot be more than the distance covered in n seconds which means the distance covered in a total time of n seconds.
