1 hour, 50 minutes, 46.15 seconds
55 km per hour = 34.18 mph
7.4 km per hour equates to 4.6 miles per hour.
46 mi/h ≈ 74.029824 km/h The formula to convert miles to km 46 mi* 63360 in 1 mi * 2.54 cm 1 in * 1 km 100000 cm = 74.029824 km
At 100 kph, it takes 10/100 = 1/10 hour.At 120 kph, it takes 10/120 = 1/12 hour.The difference is (1/10 - 1/12) = (6/60 - 5/60) = 1/60 hour = 1 minute.
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
A car covers a distance of 242 km in 2.2 hours how much distance will it cover in 1 hour
About 134 The full conversion formula to arrive at the answer: 128.74752 km/h 80 mi* 63360 in 1 mi * 2.54 cm 1 in * 1 km 100000 cm = 128.74752 km
120 km in 1 hour 20 km in (1/120) x 20 = 1/6 hour or 10 minutes
1 miles/hour = 1.6 Km/hour ======== 1 kilometer = 0.6214 miles 1 mile = 1.609 kilometers
1 mile per hour is further than 1 km per hour
1.60934 km per hour
1 knot = 1.852 km/h
170 km/h * (0.6214 miles/km) = 105.64 miles/hour
1 dm = 1/10000 km 1 sec = 1/3600 hour So 1 dm/s = (1/10000 km) / (1/3600 hour) = 3600/10000 km/h = 0.36 km/h
60 km an hour is 1 km a minute. Therefore it takes 100 minutes or 1 hour 40 minutes to travel 100 km
Note that 1 miles ≈ 1.6 km. Then: 98 miles / hour * 1.6 km / miles ≈ 157.7 km / hour
