Step-by-step explanation:
person travels 7 1/2 km = 15/2 = 7.5km
in time = 1h
speed of person = distance/time
= 7.5/1
= 7.5 km/h
in time = 3 2/5 h = 17/5 = 3.4 h
speed = distance/time
7.5 = distance /3.4
distance = 7.5×3.4
distance = 25.5 km
she covers 25.5 km distance in 3 2/5 hours.
hope it helps you :)
