Question

If person travels 7 1/2 km in one hour then what distance she will cover in 3 2/5 hours

Answer 1

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 :)
