Question

distance covered in 15 minute is 200 km what time will it take to cover 10 km

Answer 1

200km each 15 minutes to get minutes per km we do:

15/200 and we get 0.075(minute per km)

we multiply that by 10(km) = 0.75, multiplied with 60(translated to sec)

that will be 45, you need 45 sec to cover 10 km

Answer 2

15min : 200km

x min : 10km

15/200 = x/10

Cross multiplication

15*10 = 200*x

x= 150/200

x= 0.75 minute
