Answer:


  • \sf 8 \: hours

Explanation:

A goods truck travelling at 48km per hour covers a distance in 6 hours

  • Speed = 48 km/hr
  • Time = 6 hours.

Formula used :

Distance = Speed × time

= 48 × 6

= 288 km

If the speed of the truck decreases to 36km per hour.

  • Speed = 36 km/hr
  • Distance = 288 km

Distance = Speed × time

288 = 36 × time

time = 288/36

time = 8 hours

Answer:

  • 8 hours

--------------------

The distance is:

  • distance = speed × time

Substitute values:

  • distance = 48 × 6
  • distance = 288 km

Now, using same formula, find the time with the decreased speed:

  • time = distance / speed

Substitute values:

  • time = 288 / 36
  • time = 8 hours
