If Paul's average speed is 5 km per hour, how long would it take Paul to
walk 6.25 km?

Here, we are required to determine how long would it take Paul to walk 6.25 km.

The Time, t = 1.25hours (i.e 1 hour and 15mins)

Since Paul's average speed is 5km per hour = 5km/h

Speed is defined as the distance covered(in this case, km) per unit time(in this case, hours)

Therefore, Speed = Distance/Time.

Therefore, 5km/h = 6.25km/Time.

Therefore, the time taken for Paul to walk 6.25 km is ;

Time = (6.25/5)hours

Time, t = 1.25hours (i.e 1 hour and 15mins)
