None, but there are 450 minutes in 71/2 hoursTo find this:Divide 450 by 60 (450 / 60)That equals 7.5.But how do we calculate this as precise hours and minutes?Take 7.5; this is 7.5 hours. The .5 is a half; so what's half of an hour? 30 minutes?So this becomes 7 hours and 30 minutes.Short method:450 / 60 = 7.5 = (.5 means half so 30 mins) = 7 hours and thirty minutes.
Speed = distance/time so it is 450/5 = 90 km per hour.
252 miles in 5 hours and 15 minutes = 48 mph
20/5 = 4 miles per hour
divide 2250 by 5 to get 450
If I can travel 450 miles in 2 hours, I can travel 450 ÷ 2 = 225 miles in 1 hour. As I can travel 225 miles in each hour, I can travel 1200 miles in: 1200 ÷ 225 = 51/3 hours = 5 hours 20 minutes.

5 hours 37 minutes.
450/55=8.181818181818182 hours.
450 / 75 = 6 hours.
450 / 70 = 6.429 hours (rounded)
6.5 hours
450 miles.
The average speed of the bus would be 90 km/h (450 km divided by 5 hours).
time = distance / speed so, 450 miles / 100 mph = 4.5 hours
About 450 miles or 7 1/2 hours
