One hour at 751 mph
The distance between the two towns is 15 miles. This is determined by multiplying the average speed (45 miles per hour) by the time it takes to drive between the towns (20 minutes converted to hours is 1/3 hour). 45 miles/hour x 1/3 hour = 15 miles.
It would take approximately 7.6 hours to drive from San Francisco to Los Angeles at a constant rate of 55 miles per hour.
60 miles per hour = 48.3 kilometers per hour.
A really long time; about six months at 55 miles per hour.
To convert speed change from miles per hour per second to miles per hour squared, you would need to divide by a time unit, which in this case would be seconds. Therefore, 3.6 miles per hour per second is equivalent to 3.6 miles per hour squared.
Eleven hours.
That depends on the speed at which you are driving. For example, if you are driving 52.6 miles/hour, it would take an hour to drive that far. If you are driving 23.8 miles/hour, it would take two hours to drive that far.
3 hours 46 minutes.
42 minutes 51 seconds.
One hour.
Exactly 100 miles
It would take 1 hour 19 minutes and 38 seconds to drive 73 miles at 55 miles an hour.
1.5 hours.
"80 miles per hour" means "at the speed of 80 miles in one hour" so it would take one hour to drive 80 miles at 80 miles per hour.
That depends how fast you drive, if your average speed was 28 miles per hour it would take one hour, if your average speed doubled to 56 miles per hour it would take just half an hour.
Answer 7.5 miles an hour should do it. 7.5 miles an hour
At 60 miles an hour, 4. At forty miles an hour, 6.
