5.56 miles per hour.
To travel 200 miles at 450 mph takes 26 min 40 sec. time = distance / speed = 200 miles / (450 miles / hour) = 4/9 hour ≈ 0.444 hour 1 hour = 60 min → 4/9 hour = 4/9 × 60 min = 26 2/3 min ≈ 26.667 min 1 min = 60 sec → 2/3 min = 2/3 × 60 sec = 40 sec
Time = Distance / Speed = 1 m / 9 mph = 1/9 hour = 60/9 min ie 20/3 or 6.67 minutes.
Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
Time = Distance /Speed = 546/60 = 9.1 hours = 9 hours and 6 minutes
5.56 miles per hour.
At 60 MPH average, about 9 hr 50 min.
To travel 200 miles at 450 mph takes 26 min 40 sec. time = distance / speed = 200 miles / (450 miles / hour) = 4/9 hour ≈ 0.444 hour 1 hour = 60 min → 4/9 hour = 4/9 × 60 min = 26 2/3 min ≈ 26.667 min 1 min = 60 sec → 2/3 min = 2/3 × 60 sec = 40 sec
the speed of A is 1/9 miles per min. the speed of B is 1/8 miles per min. the speed of C is 1/10 miles per min. So, student B is the fastest.
1 hour 9 minutes 36 seconds. time = distance/speed = 87 miles / 75 mph = 1 4/25 hr = 1.16 hr 1 hr = 60 min → 0.16 hr = 0.16 × 60 min = 9.6 min 1 min = 60 sec → 0.6 min = 0.6 × 60 sec = 36 sec → 1.16 hr = 1 hr 9 min 36 sec
Time = Distance / Speed = 1 m / 9 mph = 1/9 hour = 60/9 min ie 20/3 or 6.67 minutes.
at say 50 miles per hour then just over 9 hours for example. Cannot answer exactly as speed not known. Greater speed, less time. Slower speed, more time.
Wondering the same thing. i believe you take however many miles and divide by the speed you will be averaging. so if you average a speed of 50 miles an hour it will take you approximately 9 1/2 hours. if you average a speed of 60 it will take you about 7 hours.
4 hr 9 min.
To drive 83 miles at 70 mph will take approx 1 hour 11 minutes 9 seconds. time = distance / speed = 83 miles / (70 miles/hour) = 1 13/70 hours ≈ 1.186 hours. 1 hour = 60 min → 13/70 hour = 13/70 × 60 min = 11 1/7 min ≈ 11.14 min. 1 min = 60 sec → 1/7 min = 1/7 × 60 sec = 8 4/7 sec ≈ 8.57 sec.
It depends on how fast you run. If you run at the following speeds, then it will take you a certain amount of time:5 miles / hour (8.04 km/h) - 60 min (1 hour)5.5 miles / hour (8.85 km/h) - 54 minutes 33 seconds6 miles / hour (9.66 km/h) - 50 minutes6.5 miles / hour (10.46 km/h) - 46 min 9 sec7 miles / hour (11.27 km /h) - 42 min 51 sec7.5 miles / hour (12.07 km/h) - 40 min8 miles / hour (12.87 km/h) - 37 min 30 sec8.5 miles / hour (13.67 km/h) -35 min 18 sec9 miles / hour (14.48 km/h) - 33 min 20 sec)9.5 miles / hour (15.29 km/h) - 31 min 35 sec10 miles / hour (16.09 km/h) - 30 min
1 in 9 ? in 60 Cross multiply and you will get 6.6666.
