- 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
