Because it is supposed to be difficult to win and or compete/complete
Time = Distance/Speed = 102/80 = 1.275 hours = 1 hour and 17 minutes (approx)
1 hour 27 minutes.
Speed = distance/time,65 = 102/ time time = 102/65 = 1.57 hours or about 1 hour and 34 minutes.
Dividing distance travelled by speed gives 102/65 = 1.5692307 recurring (that is, 1.5692307692307...) hours or approximately 1 hour 34 minutes.
1 km is 5/8ths of a mile. Therefore multiply 102 by 8 & divide the result by 5. 816 divided by 5 is 163.2 Km The formula to convert miles to km 102 mi* 1.609344 km 1 mi = 164.153088 km
3 miles and 102 inches is to be converted to feet.3 feet=1 yard. 1760 yards=1 mile.So 1 mile=5280 feet.5280 multiplied by 3=15840.So 3 miles=15840 feet.102 inches in feet=102 divided by 12=8.75 feet.15840+8.75=15848.75So 3 miles and 102 inches=15848.75 feet.
70 miles is 112.6 kilometers. To convert 102 kilometers to miles use the formula102 km* 1 mi 1.609344 km = 63.37986161 mi
Approximately 1 hour 20 minutes - without using a calculator !
