Question

find the speed of car in si unit if it cover 180km in 100 min.​

Answer 1

Answer:

46 km. = (180 km./hr.)t

46 km./180 km./hr. = [(180 km./hr.)t]/180 km./hr.

46/180 hr. = [(180 km./hr.)t]/180 km./hr.

46/180 hr. = (180 km./hr./180 km.)t

46/180 hr. = (1)t

t = 23/90 hr.

= (23/90 hr.)(60 min./hr.)

= 23(60/90) min.

= 23(2/3) min.

= 46/3 min.

= 15⅓ min.

= 15 min. + 1/3 min.

= 15 min. + (1/3 min.)(60 sec./min.)
