Its average speed is (3000/5) = 600 miles per hour.
(3000 miles) / (5 hours) = 600 mi/hr
Distance = Rate X Time so.... Rate = Distance/Time 210 miles/30 hours = 7 miles per hour
191.06 miles per hour.
55 miles per hour.
54.55 miles per hour.
117 / 2.25 = 52mph
I am not for sure, but im pretty sure that it is 600 miles
600 mph Average speed = Distance/Time
200 miles / 4 hours = 50 mph
DISTANCE + VELOCITY x TIME So if you travel 90 miles in two hours, 90 = velocity x 2 velocity = 45 miles per hour After 7 hours DISTANCE = 45 x 7 = 315 miles
315
600 miles per hour due West
Yes, they are proportional. Distance traveled is the velocity times the time. So if you travel at 60 miles per hour for two hours, you have gone 120 miles.
Three hours.
Distance = Rate X Time so.... Rate = Distance/Time 210 miles/30 hours = 7 miles per hour
We can only tell average speed from those two pieces of information. 3,000 miles in 5 hours equals an average speed of 600 mph.
The problem is it's useless to know either if you don't know where you are going. Speed is based on the distance traveled over time, while velocity is based on the displacement over time. That means if you drive 60 miles then turn around and return to the starting point and complete the trip in 2 hours, your average speed is 120miles traveled/2hours = 60miles per hour. But your velocity is 0 miles displaced/ 2 hours = 0 miles per hour.
With constant velocity (v) the equation for distance can be d = vt, where d is the distance traveled (in miles), and t is the time (in hours). So at t= 2 hr, d = 90 mi, solve for v = (90 mi)/(2 hr) = 45 mi/hr (or mph). Check this at 5 hours: d = (45 mi/hr)*(5 hr) = 225 mi, which checks with the original problem.
