1. Amount he has = $ 0.75
Amount he wants = $ 2.50
Amount that he needs = $( 2.50 - 0.75) = $ 1.75

2. Time taken in first half of race = 32.34 secs
Time taken in second half of race = 34.83 secs
Total time taken = (32.34 + 34.83) secs = 67.17 secs

3. Actual price of apple = $ 0.75
Amount paid by Jane = $ 5.00
