Answer:

39.375 minutes

formula's:

distance = speed * time taken

time taken = distance/speed

speed = distance/time taken

here given:

  • speed: 35 mph
  • time = 45 minutes = 0.75 hours

solve for distance:

  • distance = 35 * 0.75
  • distance = 26.25 miles

1st Street to the Boston Eatery distance is 26.25 miles, which is constant.

If speed changes to 40 mph.

  • time taken = distance/speed
  • time taken = 26.25/40
  • time taken= 0.65625 hours = 39.375 minutes
