Answer 2

Step-by-step explanation:

Given:-

a car travels 90km in 13/2 hours.

To find:-

how much time is required to cover 15km with the sale speed?

Answer:-

Time taken for 90km distance to a car

=6 1/2 hours=13/2 hours

Time taken for 1 km distance covered by the car

=>(13/2)/90

=>13/(2×90)

=>13/180 hours

Now,

Time taken for 15 km =15×(13/180) hours

=>(15×13)/180

=>13/12 hours

=>1 1/12 hours

Answer:-

Time taken for 15 km distance = 13/12 hours (or) 1 1/12 hours
