If we calculate as per an hour, he will cover 160 km in total of 8 hours at the speed of 20 km/hr and remaining 15km after that
175 = 20 * 8 + 15
He took break after every 25th km for 10 min so, he took total of (25*7 = 175 km) 7 breaks that means 70 minutes.
Hence it will take him approximately 10 hours to reach its destination.

Step-by-step explanation:
Time to cover 175 km is
time = distance/speed
= 175 km / 20 kmph
time = 8.75 hour
=6 hour 45 minute
Time which he has taken for changing horse is
= 7 × 10/60
= 1 1/6 hour
= one one by sixth hour
= 1 hour 10 minute
Total Time = 6 hour 45 minute + 1 hour 10 minute
= 7 hour 55 minute
