Now they will have eq.,

→ Shawn = 16 + 10x

→ Mark = 22 + 7x

They togetherly get their target,

→ 16+ 10x + 22 + 7x = 225

→ 38 +17x = 225

Hence, option (D) is the answer.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
