45 mph = 45 miles in an hour = 0.75 miles in a minute = 0.0625 miles in 5 seconds = 0.1 km = 100m.
45 mph = 45 miles/hour (45 miles/hour) (1hr/60 minutes) (1 minutes/60 seconds) (5 seconds) = 0.0625 miles in 5 seconds Note: If you write the fractions above with a horizontal slash instead of a diagonal slash, it is easier to see what cancels out to make this problem work the way it does.
45 mph (5280 feet/1 mile)(1 hour/3600 seconds) = 66 feet per second
Time = Distance/Speed = 1/45 hours = 60/45 minutes = 1.33... minutes or 1 minute 20 seconds
The speed of 45 km/h states that in every hour = 60 minutes = 3600 seconds the car travels 45 km. So in 6 seconds it travels 6/3600 = 1/600 this distance, that is: 45 x 1/600 = 45/600 = 3/40 = 0.075km = 75m.
45 mph = 45 miles in an hour = 0.75 miles in a minute = 0.0625 miles in 5 seconds = 0.1 km = 100m.
45 mph = 45 miles/hour (45 miles/hour) (1hr/60 minutes) (1 minutes/60 seconds) (5 seconds) = 0.0625 miles in 5 seconds Note: If you write the fractions above with a horizontal slash instead of a diagonal slash, it is easier to see what cancels out to make this problem work the way it does.
80 mph
going 55 mph, its around 45 seconds.
About 49 minutes 5 seconds.
1 minute 20 seconds.
60 miles
1 minute = 60 seconds 1 hour = 60 mins → 45 mins 45 seconds = 45 + 45/60 mins = (45 + 45/60)/60 hours = 61/80 hours distance = speed × time → distance = 56 mph × 61/80 hours = 42.7 miles.
At 45mph a car will travel 66 feet per second.
45 mph (5280 feet/1 mile)(1 hour/3600 seconds) = 66 feet per second
12 and 3/4 miles ....
45 mph is the same as 45 mph. How can one of the two be faster?
