Answer: 216 km/h = 134.216 mph
A
(90 mile/hour) x (1.609344 kilometer/mile) x (1 hour/3,600 sec) = 0.04023 km/sec (rounded)40.234 meters per second (rounded)
Multiply km/hr by 0.62137 mi/km to get miles per hour: 263* 0.62137 = 163.420 mph (the rough conversion is 5/8 miles per km, or 8/5 km per mile)
What is the question ? What exactly do you want to know ? How about the average speed in km per hour ? (240 km) / (4 hr) = 60 km per hour How about the average speed in miles per hour ? (60 km per hour) / (1.609344 km per mile) = 37.28 miles per hour (rounded) How about the average speed in furlongs per fortnight ? (60/1.609344 miles per hour) x (8 furlongs per mile) x (24 hours per day) x (14 days per fortnight) = 100,214.7 furlongs per fortnight (rounded)
270 km per hour is 167.8 miles per hour.
1 mile per hour is further than 1 km per hour
1.61 km/h @ 1 mile/h a kiometer is 1.6 m.p.h.
Answer: 216 km/h = 134.216 mph
One mile per hour is 1.609 km per hour. So, 40 km per hour is approximately 25 mph (exact answer is 24.86)
One mile is 1.6 km, you do the math.
1 mile = 1.60934 km So, 127 miles = 204.387 km Or, 127 miles per hour = 204.387 km per hour
1 mile = 1.609344 km 1 hour = 60 min → 40 miles per hour = 40 × 1.609344 km per hour = 64.37376 km per hour = 64.37376 km per 60 min = (64.37376 ÷ 60) km per (60 ÷ 60) min ≈ 1.073 per min.
1 mile = 1.609344 km (exactly) → 110 miles per hour = 110 x 1.609344 km per hour = 177.02784 km per hour ≈ 177 km/h
1.609 km ≈ 1 mile → 12 km/h ≈ 12 ÷ 1.609 mph ≈ 7.5 mph
Multiply miles per hour by 1.60934 to get km per hour.
