200 miles / 4 hours = 50 mph
A knot is 1 nautical mile. Therefore, 200 / 25 = 8 hours
4 more hours
Distance = Rate * Time or, for our purposes, Rate = Distance/Time Rate = 200 miles/4 hours = 50 miles per hour ==============
Your friend will have to wait one hour: Covering 200 miles at 50 miles/hour requires 4 hours, while covering the same distance at 40 miles/hour requires 5 hours.
200 hours
(200 mile)/(45 mile/hr) = 4.4444 hours = 4 hours & 26.6667 minutes
Time taken in hours = 41/200
200 / 25 = 8 hours
5 hours.
3.08 hours =3 hours 7.5 minutes
two and a half hours, 200/80 = 2.5
200 miles, 4 hours
200 miles, 4 hours
If you mean 65 miles/hour then just divide. 200 / 65 = 40 / 13 = 3.08 hours
Time = Distance / Speed 6800 miles / 200 miles per hour = 34 hours.
Time = Distance/Speed = 200/80 = 2.5 hours.
