It takes 2 hours for the bikes to cross
2h * 5 m/h = 10m
The fly has a speed of 7 m/h
2h * 7 m/h = 14m

Its really quite simple. The bikes are travelling at the same speed so they will meet at the 5 mile mark (ie in the centre). Because they are both travelling at 5 mph, it will take them an hour to complete the journey. The fly will therefore be flying for a total of one hour at 7 mph. So it will travel 7 miles in total.

wouldn't the bikes meet in 1 hour (not 2) since they each only have to cover 1/2 the distance?
