Question

A cheetah can run 103 feet per second. A zebra can run $x$ feet per second. Write and simplify an expression that represents how many feet farther the cheetah can run in 10 seconds.

Answer 1

103*10=1030.

1030-$x$ (subtract 1030 by $x$, whatever $x$ stands for. If $-$ stands for nothing, then the final answer is 1030-$x$)
