A bus is moving with a speed of \( 10 \mathrm{~m} / \mathrm{s} \) on the straight road. A scooterist wishes to overtake the bus in 50 seconds. If the bus is at a distance of \( 1 \mathrm{~km} \) from the scooterist, with what speed should the scooterist chase the bus?
a. \( 50 \mathrm{~m} / \mathrm{s} \)
b. \( 60 \mathrm{~m} / \mathrm{s} \)
c. \( 80 \mathrm{~m} / \mathrm{s} \)
d. \( 30 \mathrm{~m} / \mathrm{s} \)
