A car hire company offers two plans A and B. In plan A, a customer pays a flat fee of $20 for the day plus 5 cents for each kilometer. In plan B, a customer pays a flat fee of $15 for the day plus 7 cents for each kilometer. For how many kilometers would a customer pay the same amount for the two plans

X = number of hours
Plan A ==== > 20+0.05x 

Plan B =====> 15+0.07x
..
20+0.05x=15+0.07x
5=0.02x
multiply by 100
500 = 2x
/2
250 =x  hours
