Answer:72minutes B
Step-by-step explanation:
100t + 150t =300
250t =300
t=300/250
t=6/5 hours
Converting to minutes
6/5×60=72 minutes
Answer:
Answer is B
Step-by-step explanation:
If point D with coordinates (a,b) is reflected over the line y=x then the image point D' coordinates are (b,a) (see picture for details).
The middlepoint M of segment DD' lhas coordinates and lies on the line y=x (since its coordinates are equal), DD' is perpendicular to the line y=x and DM=D'M. All these remarks show that the point D' is the image point of D.
