  • distance/time = speed

TO FIND

  • speed = 4 km/hr

  • time = 2 + 3/4 = 11/4 hours(we reached this solution by converting 45 minutes into hours)

using the equation,,

distance = speed*time

  • distance = 4 * (11/4) km

  • distance = 11 km

✏️speed = 16.5 km/hr

☑️time = distance/speed

✏️time = (11/16.5)*60 = 40 minutes

✏️the man 40 minutes to cover the same distance with the speed of 16.5 km/hr
