a mars rover traveled from point a to point b at a speed of 4 cm/sec. Worsening conditions during the return trip caused the rover to travel at a speed of 2.5cm/sec and increased the travel time by 15 minutes. what is the distance between point a and point b?

Respuesta :

Answer: 60 meters

Step-by-step explanation:

Let x be distance

4x = 2.5x + 15

Convert everything into seconds:

4cm/sec = 2.5 cm/sec + 15 * 60

4x = 2.5x + 900

Then you solve the problem:

x=600

Then convert into meters:

x=60 meters
