Given parameters:
Distance traveled = 1778miles
Average speed = 61.7 miles per hour
Unknown:
Time taken for the travel = ?
Speed is a physical quantity. It is the rate of change of distance with time.
It can be mathematically expressed as;
Speed = 
The unknown here is the time taken;
Substitute the parameters and solve for it;
61.7 =
time taken =
= 28.8hrs
The time taken is 28.8hrs
