Question

a person reaches his office 15 minutes late if he goes at 60 km/hr he is early by 9 minutes if he goes at 100 km/ h. Find speed required to reach office in time?​

Answer 1

Step-by-step explanation:

time difference 15 min late + 9min early = 24 min

he reaches before 24 min if ge increased speed by 40 km/hr

for reaching 15 min early he has to increase speed by 40/24 × 15 = 25 km/hr

he has to increase his speed by 25 km/hr

60+25 = 75km/hr
