Question

4) If an object is traveling at a speed of 400 m/s, how long (in hours) will it take to reach 950.5 km?

Answer 1

Answer:

Answer: 0.66 hours

Explanation:

${ \rm{time = \frac{distance}{speed} }} \\ \\ { \rm{time = \frac{(950.5 \times 1000) \: m}{400 \: m {s}^{ - 1} } }} \\ \\ { \rm{time = {2376.25 \: s}}}$

• Remember 1 second accounts for 1/3600 hours

${ \rm{time = \frac{2376.25}{3600} }} \\ \\ { \rm{time = 0.66 \: hours}}$
