Rate = Distance / Time
Time = 1.5 hours
Distance = 70 * 3 miles = 210 miles
Rate = 140 miles per hour
Average speed is 65 mph.
It's 25 miles per half-hour, and it's also 50 miles per hour.
Shayla's speed for the last half-mile was approximately 0.002 miles per second.
The easiest wau to solve this is to think of a number that both 5 and 10 go into. Say 10. Suppose each half of the race was 10 miles long. Then the first half, at 5 mph, takes 2 hours. The second half, at 10 mph takes one hour. Than makes 3 hours in all to run the 10+10 = 20 miles. So average speed = 20/3 = 6.67 mph. The required answer is known as the Harmonic mean of the two speeds.
Average speed of Cheetah = 60 mph(miles per hour) Since 30 minutes is half and hour you will halve 60 by half. 60 mph = 1 hour 60/2 = 30 mph Answer - The cheetah can run up to 30 miles a hour (if he maintains the speed of 60 miles a hour).
Average speed is 65 mph.
The average brisk walking speed for an adult is about 3.5 mph, so a half-hour walk at that speed would cover roughly 1.7 to 1.8 miles.
7.5 miles per hour.
It's 25 miles per half-hour, and it's also 50 miles per hour.
Shayla's speed for the last half-mile was approximately 0.002 miles per second.
Speed= Distance/Time Distance= 26 miles Time= 1/2 hour Speed=26/1/2=52 Speed= 52 miles/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.

If 114 miles/hour is an average speed of the Travel, It will take only half an hour to reach that destination.
