Step-by-step explanation:

set it,it up by 30 minutes over 4 miles and x over 6 miles then you multiply by 6 and 30 which is 180 then divide by 4 and i got 45

Answer:

  • 10 fewer minutes

Step-by-step explanation:

Use formula

  • distance = time* speed

The distance between home and school:

  • 4* 30 min = 4 * 0.5 hr = 2 miles

Noah's time to reach home:

  • 2 / 6 = 1/3 hr = 1/3*60 min = 20 min

Difference in time:

  • 30 min - 20 min = 10 min
