Question

Lincoln rode his bike 16 miles in 104 minutes. If he rode at a constant speed how far did he ride in 10 minutes

Answer 1

Use cross multiplication to solve:

$\frac{104}{10} =\frac{16}{x}\\ \\10*16=160\\104x=160\\\\x=160/104\\x=\frac{20}{13}$

So, he rode $\frac{20}{13}$ miles in 10 minutes (approximately 1.54mi).
