Jonathan increased his rate of walking by 25% at halfway to his destination and therefore arrived half an hour earlier than was planned. How long did it take for Jonathan walk to his destination?O

1.67 hours

Step-by-step explanation:

Let the original speed of Jonathan = units/hr

Let the original time taken by Jonathan = hours

Let the distance = units

Formula for distance is given as:

Given that half the distance is covered by original speed.

Half the distance is covered by increasing the rate by 25%.

i.e. increased speed:

Hence, Time taken:

Distance traveled is half of the total distance:

Dividing (1) by (2):

345
