10 minutes.
At 8 MPH, you would cover a mile in 1/8th of an hour, or: 60minutes/8=7.5 minutes
90 seconds
If you are going 70mph it would take you 1 hour
3.86 hours Assumption: speed is constant at 70 mph for the entire 270 mile trip
1 mile = 1.6 km 70*1.6 = 112
If you are going "one mile per hour", it takes exactly one hour to go a mile.
for minutes and 1 sec.
That depends on how many miles per hour its traveling divided by 60
At constant speed of 60mph, it would take a car one minute to cover a mile, or 60 seconds, which is 1/60 of an hour.
10 minutes.
At 150 miles per hour you cover 2.5 miles per minute thus to cover 1 mile will take 0.4minutes or 24 seconds
At 8 MPH, you would cover a mile in 1/8th of an hour, or: 60minutes/8=7.5 minutes
45 seconds.
